Introduction: Sanskrit language has scripts or alphabets for writing, and grammatical rules for sentence formation, just like any other language (English for example). In this chapter we will get an overview of this. The details with their grammatical rules will be covered in subsequent chapters.

Alphabets & Their Classification: In Sanskrit language Devanagari Script is the mostly used script for writing. Most of the Sanskrit literature are in this script. Following is the list of the alphabets in their correct order.

All these alphabets are classified into two major groups i.e.,

• Vowels or स्वरवर्ण (svaravarNa): Alphabets starting from अ (a) till औ (au) are the vowels. These are further classified into ह्रस्व (hrasva) and दीर्घ (diirgha). The दीर्घ (diirgha) are pronounced double the length (or time) of ह्रस्व (hrasva). 
  
  

  ह्रस्व  hrasva	अ a	आ aa	इ i	उ u	ए e	ऐ ai	ओ o	औ au
  दीर्घ diirgha	ई ii	ऊ uu	ऋ RRi	ॠ RRI

• Consonants or व्यञ्जनवर्ण (vyaJNjanavarNa): Alphabets starting from क (k) till ज्ञ (dny) are the consonants. Some of the consonants are further classified into different groups called वर्ग (varga). Following table has this classification. Some of the gramatical rules for Euphonic Combination or सन्धि (sandhi) and Compound Words or समास (samaasa) are based on these वर्ग (varga). 
  
  

  कवर्ग kavarga	क k	ख kh	ग g	घ gh	ङ N^
  चवर्ग chaavarga	च ch	छ chh	ज j	झ jh	ञ JN
  टवर्ग Taavarga	ट T	ठ Th	ड D	ढ Dh	ण N
  तवर्ग tavarga	त t	थ th	द d	ध dh	न n
  पवर्ग pavarga	प p	फ ph	ब b	भ bh	म m

We will refere these classifications, while covering the Euphonic Combination or सन्धि (sandhi) and Compound Words or समास (samaasa).

Sentence Formation Overview: In Sanskrit just like any other language (English for example) a sentence is made of different elements. The elements are "Subject", "Object", and "Verb". A sentence may or may not have an Object in it. 

Lets study the following English sentence to understand these basic elements better.

        The boy is reading a book.

In the sentence "boy" is the "Subject", "reading" is "Verb" and the "book" is the "Object".

        The boy is               reading               a book.             ---                  -------                 -----           |                      |                      |          Subject                  Verb                  Object 

• Similarly the answer to "what is the boy reading?" is "book". The "book" becomes the "Object".

Now study the following statement.

        The boy is laughing.

In the sentence "boy" is the "Subject", "laughing" is "Verb". But, there is no "Object" in this sentence.

        The boy is               laughing.             ---                  -------             |                      |           Subject                  Verb 

• However in the first sentence "what is the boy reading?" gives answer "book". In this case the "reading" becomes a "Transitive Verb".

Now that we have understood the basic elements of a sentence, we will begin with more details of Sanskrit language. 

In Sanskrit:

• Subject is called -> कर्ता / kartaa
• Object is called  -> कर्म / karma
• Verb is called    -> क्रिया / kriyaa
• Transitive Verb is called   -> सकर्मक / sakarmaka
• Intransitive Verb is called -> अकर्मक / akarmaka

So, in the above statements:

        The boy is               reading                      a book.             ---                  -------                        -----             |                      |                             |          Subject                  Verb                         Object            |                      |                             |          कर्ता/kartaa               क्रिया/kriyaa(सकर्मक / sakarmaka)   कर्म/karma  

        The boy is               laughing.             ---                  -------             |                      |           Subject                  Verb        |                      |          कर्ता/kartaa               क्रिया/kriyaa (अकर्मक / akarmaka) 

Words & Their Classification: In any language a sentence is madeup of multiple words composed in a well defined structure giving a sensible meaning to the sentence. These words can be categorised into three different types viz.,

• Noun
• Verb
• Indeclinable

Besides the above classifications nouns and verbs can also be part of following categories with minor derivations like addition of 'ility', 'ily', 'tion', 'ing' etc., as well as based on their usage and grammatical rules:

• Pronoun
• Adjective
• Adverb

In Sanskrit also words are classified into similar categories. Following is a representation of the important classifications. We can see the classification is almost same as any other language. Each classification has been described in the coming chapters.

Nouns (शब्द / shabda): Noun is the word that represents someone or something in a sentence. Noun normally refers to person, place, thing, state or quality etc. A noun is the only word that can be used as the subject or object for a verb.

Noun in Sanskrit is called शब्द (shabda) or noun-root. It is also called कर्तृपद (kartRRipada). Noun can be classified into सुवन्तपद (suvantapada) and तद्धितपद (taddhitapada). 

• सुवन्तपद (suvantapada): This classification is based on the gender, number and case of the noun. The noun-forms are used to express something or someone etc. सुवन्तपद or suvantapada meaning - words ending with सुप् (sup) suffix. In this classification: 
  
  
  • Nouns are categorised into three different "genders" (लिङ्ग / liN^ga) viz., "masculine" (पुंलिङ्ग / pu.nliN^ga), "feminine" (स्त्रीलिङ्ग / striiliN^ga) and "neuter" (नपुंसकलिङ्ग / napu.nsakaliN^ga).
    
    
  • Each noun also has three "numbers" (वचन / vachana) and 7 "cases" (विभक्ति / vibhakti).
  
  
  Each noun has a different derivation based on the "number" and "case". Unlike other languages, in Sanskrit the noun has its different forms built into itself. The "noun base" is called शब्द (shabda) and the "derived noun forms" are called शब्दरुप (shabdarupa). So, in the previous statement बालक is the "base" (शब्द / shabda) of noun "BOY" and बालकः is one of the derived noun forms (शब्दरुप / shabdarupa). 
  
  
• तद्धितपद (taddhitapada): In this classification special suffixes are added to the noun to get noun forms used as - subject, adjectives, indeclinable etc.

We will start with first 2 cases and all three numbers of सुवन्तपद (suvantapada) BOY (बालक / baalaka) and GIRL (वाला / vaalaa) शब्द / shabda. Once we know how to use noun forms (शब्दरुप / shabdarupa) in sentences, we will cover all the cases and their usage rules. 

Examples of noun form (शब्दरुप / shabdarupa):

• The boy     -> बालकः  / baalakaH
• Many boys   -> बालकाः  / baalakaaH
• To the boy  -> बालकम्  / baalakam
• To the boys -> बालकान्  / baalakaan
• The girl     -> बाला   / baalaa
• Many girls   -> बालाः  / baalaaH
• To the girl  -> बालाम्  / baalaam
• To the girls -> बालाः  / baalaaH

The complete noun form (शब्दरुप / shabdarupa) for बालक शब्द (baalaka shabda) will have 7 different forms for each number. The singular forms include "the boy", "to the boy", "by the boy", "for/tothe boy", "from the boy", "of the boy", and "in the boy". Besides these 7 forms an additional vocative ("O! boy") case is also their. 

All these we will study in detail in coming chapters. The complete शब्दरुप (shabdarupa) is listed in Chapter 13.

Followings are few more nouns (शब्दरुप / shabdarupa). We will use these in sentences later in this chapter. 

Pronouns (सर्वनाम पद / sarvanaama pada): Words like he, she, this, that, these etc., are called pronoun. Pronouns in Sanskrit are called सर्वनाम पद (sarvanaama pada). The rules for pronouns are exactly same as the nouns (शब्द / shabda).

Verb (धातु / dhaatu): Verb normally refers to action, state, existence or occurrence etc. Verb in Sanskrit is called धातु (dhaatu) or verb root. It is also known as क्रियापद (kriyaapada). It can beclassified into तिङतपद (tiN^atapada) and कृदन्तपद (kRRidantapada). 

• तिङतपद (tiN^atapada): This classification is based on the tense and mood of the verb. The verb-forms are used as normal verbs to express some action or state etc. तिङतपद or tiN^atapada meaning - words ending with तिप् (tip) suffix. In this classification: 
  
  
  • Each Verb can have any of the 10 tenses (लकार / lakaara). Howver only 5 are enough to use Sanskrit in daily life. 
    
    
  • Each verb can be of three different numbers, Singular (एकवचन / ekavachana), Dual (द्वीवचन / dviivachana) and Plural (बहुवचन / bahuvachana). 
    
    
  • Each verb can be of three persons viz., Third (प्रथम / prathama), Second (मध्यम / madhyama) and First (उत्तम / uttama). 
    
    
  • Each verb can belong to categories परस्मैपदी (parasmaipadii), आत्मनेपदी (aatmanepadii) or उभयपदी (ubhayapadii). Verbs of परस्मैपदी (parasmaipadii) category represent 'action whose result is for others'. आत्मनेपदी (aatmanepadii) represents 'action whose result is for self', and उभयपदी (ubhayapadii) represents 'action whose result is both for others and self'.
    
    
  Just like noun (शब्द / shabda), each verb (धातु / dhaatu) also has different derivations based on the "tense", "number' and "person". This is called "verb form" (धातुरुप / dhaaturupa). The verb-forms differ based on this category. The "root" of a verb is called धातु (dhaatu). धातु (dhaatu) does not have any "gender". 
  
  
• कृदन्तपद (kRRidantapada): In this classification special suffixes are added to the verb to get verb-forms used as - subject, pronoun, adjectives, indeclinable etc.

Followings are the तिङतपद (tiN^atapada) verb-forms (धातुरुप / dhaatutupa) of READ (पठ् / paTH) धातु (dhaatu) and GO (गम् / gam) धातु (dhaatu) in present tense (लट्लकार / laTlakaara). Once we are acquainted with the verb usage in a sentence, we will cover all other different forms.

Lets study a sample use of shabdarupa and dhaaturupa using the above. These will help in learning the sentence formation rules. 

        the boy is reading   - बालकः पठति / baalakaH paThati         the boys are reading - बालकाः पठन्ति / baalakaaH paThanti

        the girl is reading   - बाला पठति / baala paThati         the girls are reading - बालाः पठन्ति / baalaaH paThanti                  you are reading     - त्वं पठसि / tvam   paThasi         you all are reading - युयं पठथ / yuyam paThata

        i am reading   - अहं पठामि / aham paThaami         we are reading - वयं पठामः / vayam paThaamaH 

All the sentences above have the "Subject" (कर्ता / kartaa) and a "Verb" (क्रिया / kriyaa). In all the sentences, the number (वचन / vachana) and person (पुरुष / puruSha) of the "Verb" (क्रिया / kriyaa) match number (वचन / vachana) and person (पुरुष / puruSha) of the "Subject" (कर्ता / kartaa). 



Say in the sentence "the boy is reading" (बालकः पठति / baalakaH paThati), the "boy" (बालकः / baalakaH) is in third person singular (प्रथपपुरुष एकवचन / prathamapuruSha ekavachana). Similarly the "Verb" (क्रिया / kriyaa) is also in third person singular (प्रथपपुरुष एकवचन / prathamapuruSha ekavachana). 



However the verb does not change if the gender of the "Subject" change. This can be seen in the sentence "the girl is reading" (बाला पठति / baalaa paThati).



Rule 1: The verb (धातु / dhaatu) always follows number (वचन / vachana) and person (पुरुष / puruSha) of the noun (शब्द / shabda). 

Rule 2: The verb (धातु / dhaatu) remains same irrespective of the gender (लिङ्ग / liN^ga) of the "Subject" (कर्ता / kartaa). 

Rule 3: The verb form (धातुरुप / dhaaturupa) is always in second person (मध्यमपुरुष / madhyamapuruSha), if the noun used is अस्मद् शब्द (asmad shabda). The verb form (धातुरुप / dhaaturupa) is always in first person (उत्तमपुरुष / uttamapuruSha), if the noun used is युस्मद् शब्द (yusmad shabda). All other nouns will always be in third person (प्रथमपुरुष / prathamapuruSha).

Indeclinable (अव्ययपद / avyayapada): Indeclinable in Sanskrit is called अव्ययपद (avyayapada). Unlike shabdarupa and dhaaturupa अव्ययपद / avyayapada do not change in its form. It remains same irrespective of gender, number, person and tense. Followings are few examples: 

           kutra / कुत्र   - where            atra / कुत्र     - here            tatra / तत्र   - there            api / अपि      - too 

Few sample statements using indeclinable (अव्ययपद / avyayapada):

           where is the boy going   - बालकः कुत्र गच्छति / baalakaH kutra gachchhati            the boy is going there   - बालकः तत्र गच्छति / baalakaH tatra gachchhati                        where are the boys going - बालकाः कुत्र गच्छन्ति / baalakaaH kutra gachchhanti            the boys are going there - बालकाः तत्र गच्छन्ति / baalakaaH tatra gachchhanti 

Note that the अव्ययपद (avyayapada) remains the same irrespective of the number, and person of the "Subject" (कर्ता / kartaa). 

Rule 4: Indeclinables (अव्ययपद / avyayapada) never change in form and remain same irrespective of the person and number of the "Subject" (कर्ता /kartaa).

Adjective (विशेषण / visheShaNa): Adjective is the word that expresses an attribute or property of something or someone. Only nouns can be used adjectives. In Sanskrit it is called विशेषण (visheShaNa). Adjective always follows the gender (लिङ्ग / liN^ga) and number (वचन / vachana) of the subject or the word for which it is an adjective. Followings are few examples:

           blue sky    - निलः आकाशः / nilaH aakaashaH            white cloud - स्वेतः मेघः / svetaH meghaH 

In above sentences the words blue and white represent an attribute of sky and cloud. So, these are adjectives for the words sky and cloud respectively.

Voice (वाच्य / vaachya): In Sanskrit sentence can be in any of the following three voices. 'Impersonal Voice' is specific to Sanskrit language only and this sentence formation is normally not seen in other languages like English.

        1. Active voice or कर्तृवाच्य (kartRRI vaachya).         2. Passive voice or कर्मवाच्य  (karma vaachya).         3. Impersonal voice or भाववाच्य (bhava vaachya). 

Now that we know the basics of Sanskrit sentence formation, their different elements, classification of alphabets and words, we will study the rules in detail in subsequent chapters.

Introduction: Sanskrit language has scripts or alphabets for writing, and grammatical rules for sentence formation, just like any other language (English for example). In this chapter we will get an overview of this. The details with their grammatical rules will be covered in subsequent chapters.

Alphabets & Their Classification: In Sanskrit language Devanagari Script is the mostly used script for writing. Most of the Sanskrit literature are in this script. Following is the list of the alphabets in their correct order.

All these alphabets are classified into two major groups i.e.,

• Vowels or स्वरवर्ण (svaravarNa): Alphabets starting from अ (a) till औ (au) are the vowels. These are further classified into ह्रस्व (hrasva) and दीर्घ (diirgha). The दीर्घ (diirgha) are pronounced double the length (or time) of ह्रस्व (hrasva). 
  
  

  ह्रस्व  hrasva	अ a	आ aa	इ i	उ u	ए e	ऐ ai	ओ o	औ au
  दीर्घ diirgha	ई ii	ऊ uu	ऋ RRi	ॠ RRI

• Consonants or व्यञ्जनवर्ण (vyaJNjanavarNa): Alphabets starting from क (k) till ज्ञ (dny) are the consonants. Some of the consonants are further classified into different groups called वर्ग (varga). Following table has this classification. Some of the gramatical rules for Euphonic Combination or सन्धि (sandhi) and Compound Words or समास (samaasa) are based on these वर्ग (varga). 
  
  

  कवर्ग kavarga	क k	ख kh	ग g	घ gh	ङ N^
  चवर्ग chaavarga	च ch	छ chh	ज j	झ jh	ञ JN
  टवर्ग Taavarga	ट T	ठ Th	ड D	ढ Dh	ण N
  तवर्ग tavarga	त t	थ th	द d	ध dh	न n
  पवर्ग pavarga	प p	फ ph	ब b	भ bh	म m

We will refere these classifications, while covering the Euphonic Combination or सन्धि (sandhi) and Compound Words or समास (samaasa).

Sentence Formation Overview: In Sanskrit just like any other language (English for example) a sentence is made of different elements. The elements are "Subject", "Object", and "Verb". A sentence may or may not have an Object in it. 

Lets study the following English sentence to understand these basic elements better.

        The boy is reading a book.

In the sentence "boy" is the "Subject", "reading" is "Verb" and the "book" is the "Object".

        The boy is               reading               a book.             ---                  -------                 -----           |                      |                      |          Subject                  Verb                  Object 

• Similarly the answer to "what is the boy reading?" is "book". The "book" becomes the "Object".

Now study the following statement.

        The boy is laughing.

In the sentence "boy" is the "Subject", "laughing" is "Verb". But, there is no "Object" in this sentence.

        The boy is               laughing.             ---                  -------             |                      |           Subject                  Verb 

• However in the first sentence "what is the boy reading?" gives answer "book". In this case the "reading" becomes a "Transitive Verb".

Now that we have understood the basic elements of a sentence, we will begin with more details of Sanskrit language. 

In Sanskrit:

• Subject is called -> कर्ता / kartaa
• Object is called  -> कर्म / karma
• Verb is called    -> क्रिया / kriyaa
• Transitive Verb is called   -> सकर्मक / sakarmaka
• Intransitive Verb is called -> अकर्मक / akarmaka

So, in the above statements:

        The boy is               reading                      a book.             ---                  -------                        -----             |                      |                             |          Subject                  Verb                         Object            |                      |                             |          कर्ता/kartaa               क्रिया/kriyaa(सकर्मक / sakarmaka)   कर्म/karma  

        The boy is               laughing.             ---                  -------             |                      |           Subject                  Verb        |                      |          कर्ता/kartaa               क्रिया/kriyaa (अकर्मक / akarmaka) 

Words & Their Classification: In any language a sentence is madeup of multiple words composed in a well defined structure giving a sensible meaning to the sentence. These words can be categorised into three different types viz.,

• Noun
• Verb
• Indeclinable

Besides the above classifications nouns and verbs can also be part of following categories with minor derivations like addition of 'ility', 'ily', 'tion', 'ing' etc., as well as based on their usage and grammatical rules:

• Pronoun
• Adjective
• Adverb

In Sanskrit also words are classified into similar categories. Following is a representation of the important classifications. We can see the classification is almost same as any other language. Each classification has been described in the coming chapters.

Nouns (शब्द / shabda): Noun is the word that represents someone or something in a sentence. Noun normally refers to person, place, thing, state or quality etc. A noun is the only word that can be used as the subject or object for a verb.

Noun in Sanskrit is called शब्द (shabda) or noun-root. It is also called कर्तृपद (kartRRipada). Noun can be classified into सुवन्तपद (suvantapada) and तद्धितपद (taddhitapada). 

• सुवन्तपद (suvantapada): This classification is based on the gender, number and case of the noun. The noun-forms are used to express something or someone etc. सुवन्तपद or suvantapada meaning - words ending with सुप् (sup) suffix. In this classification: 
  
  
  • Nouns are categorised into three different "genders" (लिङ्ग / liN^ga) viz., "masculine" (पुंलिङ्ग / pu.nliN^ga), "feminine" (स्त्रीलिङ्ग / striiliN^ga) and "neuter" (नपुंसकलिङ्ग / napu.nsakaliN^ga).
    
    
  • Each noun also has three "numbers" (वचन / vachana) and 7 "cases" (विभक्ति / vibhakti).
  
  
  Each noun has a different derivation based on the "number" and "case". Unlike other languages, in Sanskrit the noun has its different forms built into itself. The "noun base" is called शब्द (shabda) and the "derived noun forms" are called शब्दरुप (shabdarupa). So, in the previous statement बालक is the "base" (शब्द / shabda) of noun "BOY" and बालकः is one of the derived noun forms (शब्दरुप / shabdarupa). 
  
  
• तद्धितपद (taddhitapada): In this classification special suffixes are added to the noun to get noun forms used as - subject, adjectives, indeclinable etc.

We will start with first 2 cases and all three numbers of सुवन्तपद (suvantapada) BOY (बालक / baalaka) and GIRL (वाला / vaalaa) शब्द / shabda. Once we know how to use noun forms (शब्दरुप / shabdarupa) in sentences, we will cover all the cases and their usage rules. 

Examples of noun form (शब्दरुप / shabdarupa):

• The boy     -> बालकः  / baalakaH
• Many boys   -> बालकाः  / baalakaaH
• To the boy  -> बालकम्  / baalakam
• To the boys -> बालकान्  / baalakaan
• The girl     -> बाला   / baalaa
• Many girls   -> बालाः  / baalaaH
• To the girl  -> बालाम्  / baalaam
• To the girls -> बालाः  / baalaaH

The complete noun form (शब्दरुप / shabdarupa) for बालक शब्द (baalaka shabda) will have 7 different forms for each number. The singular forms include "the boy", "to the boy", "by the boy", "for/tothe boy", "from the boy", "of the boy", and "in the boy". Besides these 7 forms an additional vocative ("O! boy") case is also their. 

All these we will study in detail in coming chapters. The complete शब्दरुप (shabdarupa) is listed in Chapter 13.

Followings are few more nouns (शब्दरुप / shabdarupa). We will use these in sentences later in this chapter. 

Pronouns (सर्वनाम पद / sarvanaama pada): Words like he, she, this, that, these etc., are called pronoun. Pronouns in Sanskrit are called सर्वनाम पद (sarvanaama pada). The rules for pronouns are exactly same as the nouns (शब्द / shabda).

Verb (धातु / dhaatu): Verb normally refers to action, state, existence or occurrence etc. Verb in Sanskrit is called धातु (dhaatu) or verb root. It is also known as क्रियापद (kriyaapada). It can beclassified into तिङतपद (tiN^atapada) and कृदन्तपद (kRRidantapada). 

• तिङतपद (tiN^atapada): This classification is based on the tense and mood of the verb. The verb-forms are used as normal verbs to express some action or state etc. तिङतपद or tiN^atapada meaning - words ending with तिप् (tip) suffix. In this classification: 
  
  
  • Each Verb can have any of the 10 tenses (लकार / lakaara). Howver only 5 are enough to use Sanskrit in daily life. 
    
    
  • Each verb can be of three different numbers, Singular (एकवचन / ekavachana), Dual (द्वीवचन / dviivachana) and Plural (बहुवचन / bahuvachana). 
    
    
  • Each verb can be of three persons viz., Third (प्रथम / prathama), Second (मध्यम / madhyama) and First (उत्तम / uttama). 
    
    
  • Each verb can belong to categories परस्मैपदी (parasmaipadii), आत्मनेपदी (aatmanepadii) or उभयपदी (ubhayapadii). Verbs of परस्मैपदी (parasmaipadii) category represent 'action whose result is for others'. आत्मनेपदी (aatmanepadii) represents 'action whose result is for self', and उभयपदी (ubhayapadii) represents 'action whose result is both for others and self'.
    
    
  Just like noun (शब्द / shabda), each verb (धातु / dhaatu) also has different derivations based on the "tense", "number' and "person". This is called "verb form" (धातुरुप / dhaaturupa). The verb-forms differ based on this category. The "root" of a verb is called धातु (dhaatu). धातु (dhaatu) does not have any "gender". 
  
  
• कृदन्तपद (kRRidantapada): In this classification special suffixes are added to the verb to get verb-forms used as - subject, pronoun, adjectives, indeclinable etc.

Followings are the तिङतपद (tiN^atapada) verb-forms (धातुरुप / dhaatutupa) of READ (पठ् / paTH) धातु (dhaatu) and GO (गम् / gam) धातु (dhaatu) in present tense (लट्लकार / laTlakaara). Once we are acquainted with the verb usage in a sentence, we will cover all other different forms.

Lets study a sample use of shabdarupa and dhaaturupa using the above. These will help in learning the sentence formation rules. 

        the boy is reading   - बालकः पठति / baalakaH paThati         the boys are reading - बालकाः पठन्ति / baalakaaH paThanti

        the girl is reading   - बाला पठति / baala paThati         the girls are reading - बालाः पठन्ति / baalaaH paThanti                  you are reading     - त्वं पठसि / tvam   paThasi         you all are reading - युयं पठथ / yuyam paThata

        i am reading   - अहं पठामि / aham paThaami         we are reading - वयं पठामः / vayam paThaamaH 

All the sentences above have the "Subject" (कर्ता / kartaa) and a "Verb" (क्रिया / kriyaa). In all the sentences, the number (वचन / vachana) and person (पुरुष / puruSha) of the "Verb" (क्रिया / kriyaa) match number (वचन / vachana) and person (पुरुष / puruSha) of the "Subject" (कर्ता / kartaa). 



Say in the sentence "the boy is reading" (बालकः पठति / baalakaH paThati), the "boy" (बालकः / baalakaH) is in third person singular (प्रथपपुरुष एकवचन / prathamapuruSha ekavachana). Similarly the "Verb" (क्रिया / kriyaa) is also in third person singular (प्रथपपुरुष एकवचन / prathamapuruSha ekavachana). 



However the verb does not change if the gender of the "Subject" change. This can be seen in the sentence "the girl is reading" (बाला पठति / baalaa paThati).



Rule 1: The verb (धातु / dhaatu) always follows number (वचन / vachana) and person (पुरुष / puruSha) of the noun (शब्द / shabda). 

Rule 2: The verb (धातु / dhaatu) remains same irrespective of the gender (लिङ्ग / liN^ga) of the "Subject" (कर्ता / kartaa). 

Rule 3: The verb form (धातुरुप / dhaaturupa) is always in second person (मध्यमपुरुष / madhyamapuruSha), if the noun used is अस्मद् शब्द (asmad shabda). The verb form (धातुरुप / dhaaturupa) is always in first person (उत्तमपुरुष / uttamapuruSha), if the noun used is युस्मद् शब्द (yusmad shabda). All other nouns will always be in third person (प्रथमपुरुष / prathamapuruSha).

Indeclinable (अव्ययपद / avyayapada): Indeclinable in Sanskrit is called अव्ययपद (avyayapada). Unlike shabdarupa and dhaaturupa अव्ययपद / avyayapada do not change in its form. It remains same irrespective of gender, number, person and tense. Followings are few examples: 

           kutra / कुत्र   - where            atra / कुत्र     - here            tatra / तत्र   - there            api / अपि      - too 

Few sample statements using indeclinable (अव्ययपद / avyayapada):

           where is the boy going   - बालकः कुत्र गच्छति / baalakaH kutra gachchhati            the boy is going there   - बालकः तत्र गच्छति / baalakaH tatra gachchhati                        where are the boys going - बालकाः कुत्र गच्छन्ति / baalakaaH kutra gachchhanti            the boys are going there - बालकाः तत्र गच्छन्ति / baalakaaH tatra gachchhanti 

Note that the अव्ययपद (avyayapada) remains the same irrespective of the number, and person of the "Subject" (कर्ता / kartaa). 

Rule 4: Indeclinables (अव्ययपद / avyayapada) never change in form and remain same irrespective of the person and number of the "Subject" (कर्ता /kartaa).

Adjective (विशेषण / visheShaNa): Adjective is the word that expresses an attribute or property of something or someone. Only nouns can be used adjectives. In Sanskrit it is called विशेषण (visheShaNa). Adjective always follows the gender (लिङ्ग / liN^ga) and number (वचन / vachana) of the subject or the word for which it is an adjective. Followings are few examples:

           blue sky    - निलः आकाशः / nilaH aakaashaH            white cloud - स्वेतः मेघः / svetaH meghaH 

In above sentences the words blue and white represent an attribute of sky and cloud. So, these are adjectives for the words sky and cloud respectively.

Voice (वाच्य / vaachya): In Sanskrit sentence can be in any of the following three voices. 'Impersonal Voice' is specific to Sanskrit language only and this sentence formation is normally not seen in other languages like English.

        1. Active voice or कर्तृवाच्य (kartRRI vaachya).         2. Passive voice or कर्मवाच्य  (karma vaachya).         3. Impersonal voice or भाववाच्य (bhava vaachya). 

Now that we know the basics of Sanskrit sentence formation, their different elements, classification of alphabets and words, we will study the rules in detail in subsequent chapters.

{S_Content_ChapterNavigator |<< |Index |>> }

Introduction: Sanskrit language has scripts or alphabets for writing, and grammatical rules for sentence formation, just like any other language (English for example). In this chapter we will get an overview of this. The details with their grammatical rules will be covered in subsequent chapters.

Alphabets & Their Classification: In Sanskrit language Devanagari Script is the mostly used script for writing. Most of the Sanskrit literature are in this script. Following is the list of the alphabets in their correct order.

All these alphabets are classified into two major groups i.e.,

• Vowels or स्वरवर्ण (svaravarNa): Alphabets starting from अ (a) till औ (au) are the vowels. These are further classified into ह्रस्व (hrasva) and दीर्घ (diirgha). The दीर्घ (diirgha) are pronounced double the length (or time) of ह्रस्व (hrasva). 
  
  

  ह्रस्व  hrasva	अ a	आ aa	इ i	उ u	ए e	ऐ ai	ओ o	औ au
  दीर्घ diirgha	ई ii	ऊ uu	ऋ RRi	ॠ RRI

• Consonants or व्यञ्जनवर्ण (vyaJNjanavarNa): Alphabets starting from क (k) till ज्ञ (dny) are the consonants. Some of the consonants are further classified into different groups called वर्ग (varga). Following table has this classification. Some of the gramatical rules for Euphonic Combination or सन्धि (sandhi) and Compound Words or समास (samaasa) are based on these वर्ग (varga). 
  
  

  कवर्ग kavarga	क k	ख kh	ग g	घ gh	ङ N^
  चवर्ग chaavarga	च ch	छ chh	ज j	झ jh	ञ JN
  टवर्ग Taavarga	ट T	ठ Th	ड D	ढ Dh	ण N
  तवर्ग tavarga	त t	थ th	द d	ध dh	न n
  पवर्ग pavarga	प p	फ ph	ब b	भ bh	म m

We will refere these classifications, while covering the Euphonic Combination or सन्धि (sandhi) and Compound Words or समास (samaasa).

Sentence Formation Overview: In Sanskrit just like any other language (English for example) a sentence is made of different elements. The elements are "Subject", "Object", and "Verb". A sentence may or may not have an Object in it. 

Lets study the following English sentence to understand these basic elements better.

        The boy is reading a book.

In the sentence "boy" is the "Subject", "reading" is "Verb" and the "book" is the "Object".

        The boy is               reading               a book.             ---                  -------                 -----           |                      |                      |          Subject                  Verb                  Object 

• Similarly the answer to "what is the boy reading?" is "book". The "book" becomes the "Object".
• 
  Now study the following statement.

          The boy is laughing.

  In the sentence "boy" is the "Subject", "laughing" is "Verb". But, there is no "Object" in this sentence.

          The boy is               laughing.             ---                  -------             |                      |           Subject                  Verb 

  • If we ask the question "what is the boy laughing?", no answer comes from this. So, laughing becomes an "Intranstive Verb".
  
  
  
  • However in the first sentence "what is the boy reading?" gives answer "book". In this case the "reading" becomes a "Transitive Verb".

  Now that we have understood the basic elements of a sentence, we will begin with more details of Sanskrit language. 
  
  In Sanskrit:

  • Subject is called -> कर्ता / kartaa
  • Object is called  -> कर्म / karma
  • Verb is called    -> क्रिया / kriyaa
  • Transitive Verb is called   -> सकर्मक / sakarmaka
  • Intransitive Verb is called -> अकर्मक / akarmaka
  So, in the above statements:

          The boy is               reading                      a book.             ---                  -------                        -----             |                      |                             |          Subject                  Verb                         Object            |                      |                             |          कर्ता/kartaa               क्रिया/kriyaa(सकर्मक / sakarmaka)   कर्म/karma  

          The boy is               laughing.             ---                  -------             |                      |           Subject                  Verb        |                      |          कर्ता/kartaa               क्रिया/kriyaa (अकर्मक / akarmaka) 

  
  

  Words & Their Classification: In any language a sentence is madeup of multiple words composed in a well defined structure giving a sensible meaning to the sentence. These words can be categorised into three different types viz.,

  • Noun
  • Verb
  • Indeclinable
  
  Besides the above classifications nouns and verbs can also be part of following categories with minor derivations like addition of 'ility', 'ily', 'tion', 'ing' etc., as well as based on their usage and grammatical rules:
  • Pronoun
  • Adjective
  • Adverb
  In Sanskrit also words are classified into similar categories. Following is a representation of the important classifications. We can see the classification is almost same as any other language. Each classification has been described in the coming chapters.

  Nouns (शब्द / shabda): Noun is the word that represents someone or something in a sentence. Noun normally refers to person, place, thing, state or quality etc. A noun is the only word that can be used as the subject or object for a verb.
  
  Noun in Sanskrit is called शब्द (shabda) or noun-root. It is also called कर्तृपद (kartRRipada). Noun can be classified into सुवन्तपद (suvantapada) and तद्धितपद (taddhitapada). 
  
  
  • सुवन्तपद (suvantapada): This classification is based on the gender, number and case of the noun. The noun-forms are used to express something or someone etc. सुवन्तपद or suvantapada meaning - words ending with सुप् (sup) suffix. In this classification: 
    
    
    • Nouns are categorised into three different "genders" (लिङ्ग / liN^ga) viz., "masculine" (पुंलिङ्ग / pu.nliN^ga), "feminine" (स्त्रीलिङ्ग / striiliN^ga) and "neuter" (नपुंसकलिङ्ग / napu.nsakaliN^ga).
      
      
    • Each noun also has three "numbers" (वचन / vachana) and 7 "cases" (विभक्ति / vibhakti).
    
    
    Each noun has a different derivation based on the "number" and "case". Unlike other languages, in Sanskrit the noun has its different forms built into itself. The "noun base" is called शब्द (shabda) and the "derived noun forms" are called शब्दरुप (shabdarupa). So, in the previous statement बालक is the "base" (शब्द / shabda) of noun "BOY" and बालकः is one of the derived noun forms (शब्दरुप / shabdarupa). 
    
    
  • तद्धितपद (taddhitapada): In this classification special suffixes are added to the noun to get noun forms used as - subject, adjectives, indeclinable etc.
  
  
  We will start with first 2 cases and all three numbers of सुवन्तपद (suvantapada) BOY (बालक / baalaka) and GIRL (वाला / vaalaa) शब्द / shabda. Once we know how to use noun forms (शब्दरुप / shabdarupa) in sentences, we will cover all the cases and their usage rules. 
  
  

  Boy / बालक / baalaka (Masculine / पुंलिङ्ग / pu.nliN^ga)
  Case विभक्ति / vibhakti	Singular एकवचन / ekavachana	Dual स्विवचन / dvivachana	Plural बहुवचन / bahuvachana
  Nominative (Subject) प्रथमा / prathamaa	बालकः / baalakaH (the boy)	बालकौ / baalakau (two boys)	बालकाः / baalakaaH (the boys)
  Accusative (Object) द्वितीया / dvitiiyaa	बालकम् / baalakam (to the boy)	बालकौ / balakau (to two boys)	बालकान् / baalakaan (to the boys)

  
  
  

  Girl / बाला / baalaa (Femenine / स्त्रीलिङ्ग / striiliN^ga)
  Case विभक्ति / vibhakti	Singular एकवचन / ekavachana	Dual स्विवचन / dvivachana	Plural बहुवचन / bahuvachana
  Nominative (Subject) प्रथमा / prathamaa	बाला / baalaa (the girl)	बाले / baale (two girls)	बालाः / baalaaH (the girls)
  Accusative (Object) द्वितीया / dvitiiyaa	बालाम् / baalaam (to the girl)	बाले / balae (to two girls)	बालाः / baalaaH (to the girls)

  
  
  Examples of noun form (शब्दरुप / shabdarupa):
  • The boy     -> बालकः  / baalakaH
  • Many boys   -> बालकाः  / baalakaaH
  • To the boy  -> बालकम्  / baalakam
  • To the boys -> बालकान्  / baalakaan
  • The girl     -> बाला   / baalaa
  • Many girls   -> बालाः  / baalaaH
  • To the girl  -> बालाम्  / baalaam
  • To the girls -> बालाः  / baalaaH
  The complete noun form (शब्दरुप / shabdarupa) for बालक शब्द (baalaka shabda) will have 7 different forms for each number. The singular forms include "the boy", "to the boy", "by the boy", "for/tothe boy", "from the boy", "of the boy", and "in the boy". Besides these 7 forms an additional vocative ("O! boy") case is also their. 
  
  All these we will study in detail in coming chapters. The complete शब्दरुप (shabdarupa) is listed in Chapter 13.

  Followings are few more nouns (शब्दरुप / shabdarupa). We will use these in sentences later in this chapter.

  Accusative द्वितीया / dvitiiyaa	त्वाम् / tvaam त्वा / tvaa	युवाम् / yuvaam वाम् / vaam	युष्मान् / yuShmaan वः / vaH

  
  
  

  Pronouns (सर्वनाम पद / sarvanaama pada): Words like he, she, this, that, these etc., are called pronoun. Pronouns in Sanskrit are called सर्वनाम पद (sarvanaama pada). The rules for pronouns are exactly same as the nouns (शब्द / shabda).

  Verb (धातु / dhaatu): Verb normally refers to action, state, existence or occurrence etc. Verb in Sanskrit is called धातु (dhaatu) or verb root. It is also known as क्रियापद (kriyaapada). It can beclassified into तिङतपद (tiN^atapada) and कृदन्तपद (kRRidantapada). 
  
  

  • तिङतपद (tiN^atapada): This classification is based on the tense and mood of the verb. The verb-forms are used as normal verbs to express some action or state etc. तिङतपद or tiN^atapada meaning - words ending with तिप् (tip) suffix. In this classification: 
    
    
    • Each Verb can have any of the 10 tenses (लकार / lakaara). Howver only 5 are enough to use Sanskrit in daily life. 
      
      
    • Each verb can be of three different numbers, Singular (एकवचन / ekavachana), Dual (द्वीवचन / dviivachana) and Plural (बहुवचन / bahuvachana). 
      
      
    • Each verb can be of three persons viz., Third (प्रथम / prathama), Second (मध्यम / madhyama) and First (उत्तम / uttama). 
      
      
    • Each verb can belong to categories परस्मैपदी (parasmaipadii), आत्मनेपदी (aatmanepadii) or उभयपदी (ubhayapadii). Verbs of परस्मैपदी (parasmaipadii) category represent 'action whose result is for others'. आत्मनेपदी (aatmanepadii) represents 'action whose result is for self', and उभयपदी (ubhayapadii) represents 'action whose result is both for others and self'.
      
      
    Just like noun (शब्द / shabda), each verb (धातु / dhaatu) also has different derivations based on the "tense", "number' and "person". This is called "verb form" (धातुरुप / dhaaturupa). The verb-forms differ based on this category. The "root" of a verb is called धातु (dhaatu). धातु (dhaatu) does not have any "gender". 
    
    
  • कृदन्तपद (kRRidantapada): In this classification special suffixes are added to the verb to get verb-forms used as - subject, pronoun, adjectives, indeclinable etc.
  
  
  Followings are the तिङतपद (tiN^atapada) verb-forms (धातुरुप / dhaatutupa) of READ (पठ् / paTH) धातु (dhaatu) and GO (गम् / gam) धातु (dhaatu) in present tense (लट्लकार / laTlakaara). Once we are acquainted with the verb usage in a sentence, we will cover all other different forms.

  Read / पठ् / paTh
  Person / पुरुष / puruSha	Number / वचन / vachana
  	Singular  एकवचन / ekavachana	Dual  द्वीवचन / dviivachana	Plural  बहुवचन / bahuvachana
  Third  प्रथम / prathama	पठति / paThati (is reading)	पठतः / paThataH (both are reading)	पठन्ति / paThanti (many are reading)
  Second  मध्यम / madhyama	पठसि / paThasi (you are reading)	पठथः / paThathaH (you two are reading)	पठथ / paThatha (you all reading)
  First  उत्तम / uttama	पठामि / paThaami (i am reading)	पठावः / paThaavaH (both of us reading)	पठामः / paThaamaH (all of us reading)

  
  
  

  Go / गम् / gam
  Person / पुरुष / puruSha	Number / वचन / vachana
  	Singular  एकवचन / ekavachana	Dual  द्वीवचन / dviivachana	Plural  बहुवचन / bahuvachana
  Third  प्रथम / prathama	गच्छति / gachchhati (is going)	गच्छतः / gachchhataH (both are going)	गच्छन्ति / gachchhanti (many are going)
  Second  मध्यम / madhyama	गच्छसि / gachchhasi (you are going)	गच्छथः / gachchhathaH (you two are going)	गच्छथ / gachchhatha (you all are going)
  First  उत्तम / uttama	गच्छामि / gachchhaami (i am going)	गच्छावः / gachchhaavaH (both of us going)	गच्छामः / gachchhaamaH (all of us going)

  
  
  Lets study a sample use of shabdarupa and dhaaturupa using the above. These will help in learning the sentence formation rules. 
  
  

          the boy is reading   - बालकः पठति / baalakaH paThati         the boys are reading - बालकाः पठन्ति / baalakaaH paThanti
  
          the girl is reading   - बाला पठति / baala paThati         the girls are reading - बालाः पठन्ति / baalaaH paThanti                  you are reading     - त्वं पठसि / tvam   paThasi         you all are reading - युयं पठथ / yuyam paThata
  
          i am reading   - अहं पठामि / aham paThaami         we are reading - वयं पठामः / vayam paThaamaH 

  
  All the sentences above have the "Subject" (कर्ता / kartaa) and a "Verb" (क्रिया / kriyaa). In all the sentences, the number (वचन / vachana) and person (पुरुष / puruSha) of the "Verb" (क्रिया / kriyaa) match number (वचन / vachana) and person (पुरुष / puruSha) of the "Subject" (कर्ता / kartaa). 
  
  
  
  Say in the sentence "the boy is reading" (बालकः पठति / baalakaH paThati), the "boy" (बालकः / baalakaH) is in third person singular (प्रथपपुरुष एकवचन / prathamapuruSha ekavachana). Similarly the "Verb" (क्रिया / kriyaa) is also in third person singular (प्रथपपुरुष एकवचन / prathamapuruSha ekavachana). 
  
  
  
  However the verb does not change if the gender of the "Subject" change. This can be seen in the sentence "the girl is reading" (बाला पठति / baalaa paThati).
  
  
  
  Rule 1: The verb (धातु / dhaatu) always follows number (वचन / vachana) and person (पुरुष / puruSha) of the noun (शब्द / shabda). 
  
  Rule 2: The verb (धातु / dhaatu) remains same irrespective of the gender (लिङ्ग / liN^ga) of the "Subject" (कर्ता / kartaa). 
  
  Rule 3: The verb form (धातुरुप / dhaaturupa) is always in second person (मध्यमपुरुष / madhyamapuruSha), if the noun used is अस्मद् शब्द (asmad shabda). The verb form (धातुरुप / dhaaturupa) is always in first person (उत्तमपुरुष / uttamapuruSha), if the noun used is युस्मद् शब्द (yusmad shabda). All other nouns will always be in third person (प्रथमपुरुष / prathamapuruSha).
  
  
  

  
  
  Indeclinable (अव्ययपद / avyayapada): Indeclinable in Sanskrit is called अव्ययपद (avyayapada). Unlike shabdarupa and dhaaturupa अव्ययपद / avyayapada do not change in its form. It remains same irrespective of gender, number, person and tense. Followings are few examples: 
  
  

             kutra / कुत्र   - where            atra / कुत्र     - here            tatra / तत्र   - there            api / अपि      - too 

  
  Few sample statements using indeclinable (अव्ययपद / avyayapada):

             where is the boy going   - बालकः कुत्र गच्छति / baalakaH kutra gachchhati            the boy is going there   - बालकः तत्र गच्छति / baalakaH tatra gachchhati                        where are the boys going - बालकाः कुत्र गच्छन्ति / baalakaaH kutra gachchhanti            the boys are going there - बालकाः तत्र गच्छन्ति / baalakaaH tatra gachchhanti 

  
  
  Note that the अव्ययपद (avyayapada) remains the same irrespective of the number, and person of the "Subject" (कर्ता / kartaa). 
  
  Rule 4: Indeclinables (अव्ययपद / avyayapada) never change in form and remain same irrespective of the person and number of the "Subject" (कर्ता /kartaa).
  
  
  

  Adjective (विशेषण / visheShaNa): Adjective is the word that expresses an attribute or property of something or someone. Only nouns can be used adjectives. In Sanskrit it is called विशेषण (visheShaNa). Adjective always follows the gender (लिङ्ग / liN^ga) and number (वचन / vachana) of the subject or the word for which it is an adjective. Followings are few examples:
  
  

             blue sky    - निलः आकाशः / nilaH aakaashaH            white cloud - स्वेतः मेघः / svetaH meghaH 

  
  
  In above sentences the words blue and white represent an attribute of sky and cloud. So, these are adjectives for the words sky and cloud respectively.
  
  
  
  
  

  Voice (वाच्य / vaachya): In Sanskrit sentence can be in any of the following three voices. 'Impersonal Voice' is specific to Sanskrit language only and this sentence formation is normally not seen in other languages like English.
  
  

          1. Active voice or कर्तृवाच्य (kartRRI vaachya).         2. Passive voice or कर्मवाच्य  (karma vaachya).         3. Impersonal voice or भाववाच्य (bhava vaachya). 

  
  
  Now that we know the basics of Sanskrit sentence formation, their different elements, classification of alphabets and words, we will study the rules in detail in subsequent chapters.
