Much of Tamil grammar is extensively described in the oldest available grammar book for Tamil, the Tolkāppiyam (dated between 300 BCE and 300 CE). Modern Tamil writing is largely based on the 13th century grammar Naṉṉūl, which restated and clarified the rules of the Tolkāppiyam with some modifications.

Traditional Tamil grammar consists of five parts, namely eḻuttu, sol, poruḷ, yāppu and aṇi. Of these, the last two are mostly applicable in poetry.^[1] The following table gives additional information about these parts.

Tamil name	Meaning	Main grammar books
eḻuttu	letter	Tolkāppiyam, Nannūl
sol	word	Tolkāppiyam, Nannūl
poruḷ	content	Tolkāppiyam
yāppu	compilation	Yāpparuṅkalakkārikai
aṇi	decoration	Taṇṭiyalaṅkāram

Eḻuttu (writing) defines and describes the letters of the Tamil alphabet and their classification. It describes the nature of phonemes and their changes with respect to different conditions and locations in the text.

Sol defines the types of the words based on their meaning and the origin. It defines the gender, number, cases, tenses, classes, harmony etc. This chapter also provides rules for compounding the words.

Porul defines the contents of poetry. It gives guidance on which topic to choose for poetry based on certain conditions like the nature of the land or time or the people. It gives a distinction between Agam (internal / love life) and Puram (external / worldly life).

Yāppu defines rules for composing Traditional poetry. It defines the basic building block Asai and describes how asai should be joined to form a sīr, joining sīr for an adi.

Aṇi defines techniques used for comparing, praising and criticizing the taken topics.

The script of Tamil Language consists of 247 letters. The script falls under the category Abugida, in which consonant-vowel sequences are written as a unit. The grammar classifies the letters into two major categories.

• Prime Letters – முதலெழுத்து mutaleḻuttu
• Dependent Letters – சார்பெழுத்து sārpeḻuttu

12 vowels and 18 consonants are classified as the prime letters.

• The vowels (உயிரெழுத்துகள் uyireḻuttukaḷ): அ (a), ஆ (ā), இ (i), ஈ( ī), உ (u), ஊ (ū), எ (e), ஏ (ē), ஐ (ai), ஒ (o), ஓ (ō), ஔ (au)
• The consonants (மெய்யெழுத்துகள் meyyeḻuttukaḷ): க், ங், ச், ஞ், ட், ண், த், ந், ப், ம், ய், ர், ல், வ், ழ், ள், ற், ன்

The vowels are called uyir, meaning soul, in Tamil. The consonants are known as mey, meaning body. When the alphasyllabary is formed, the letter shall be taking the form of the consonants, that is the body, and the sound shall be that of the corresponding vowel, that is the soul.

The vowels are categorized based on the length, as short (kuril) and long(nedil). The short vowels are pronounced for a duration 1 unit, while the long vowels take two units. Based on the duration of the sound, the vowels form 5 pairs. The other two vowels ஐ(ai) and ஔ(au) are diphthongs formed by joining the letters அ(a)+இ(i) and அ(a)+உ(u). Since these two are a combination two short letters, their pronunciation takes 2 units of time, that is they fall under nedil category. ஐ(ai) and ஔ(au) can also be spelt அய் and அவ். This form is known as eḻuttuppōli and is generally not recommended.

The consonants are categorised into three groups, வல்லினம் valliṉam (hard), மெல்லினம் melliṉam (soft) and இடையினம் iṭaiyiṉam (medium), based on the nature of the sound.

valliṉam	melliṉam	iṭaiyiṉam
க் k	ங் ṅ	ய் y
ச் s	ஞ் ñ	ர் r
ட் ṭ	ண் ṇ	ல் l
த் t	ந் n	வ் v
ப் p	ம் m	ழ் ḻ
ற் ṟ[2]	ன் ṉ[3]	ள் ḷ[4]

From the 30 prime letters, the dependent letters are formed.

Tamil grammar defines 10 categories of Dependent letters.

• Alphasyllabic letters உயிர்மெய் எழுத்து uyirmey eḻuttu
• Aidam ஆய்த எழுத்து āyta eḻuttu
• Elongated vowel உயிரளபெடை uyiraḷapeṭai
• Elongated consonant ஒற்றளபெடை oṟṟaḷapeṭai
• Shortened u குற்றியலுகரம் kuṟṟiyalukaram
• Shortened i குற்றியலிகரம் kuṟṟiyalikaram
• Shortened ai ஐகாரக் குறுக்கம் aikārak kuṟukkam
• Shortened au ஔகாரக் குறுக்கம் aukārak kuṟukkam
• Shortened m மகரக்குறுக்கம் makarakkuṟukkam
• Shortened Aidam ஆய்தக்குறுக்கம் āytakkuṟukkam

The alphasyllabic letters – 216 in total – are formed by combining the consonants and the vowels. The duration of the sound is that of the vowel attached to the consonant (or the inherent vowel, in case of the pure consonants). For example, the table below shows the formation of க் based letters.

Combination	Uyirmei form	ISO 15919	IPA
க் + அ	க	ka	[kʌ]
க் + ஆ	கா	kā	[kɑː]
க் + இ	கி	ki	[ki]
க் + ஈ	கீ	kī	[kiː]
க் + உ	கு	ku	[ku], [kɯ]
க் + ஊ	கூ	kū	[kuː]
க் + எ	கெ	ke	[ke]
க் + ஏ	கே	kē	[keː]
க் + ஐ	கை	kai	[kʌj]
க் + ஒ	கொ	ko	[ko]
க் + ஓ	கோ	kō	[koː]
க் + ஔ	கௌ	kau	[kʌʋ]

Aidam is also known as தனிநிலை taṉinilai (stand alone). The aidam is always preceded by a single short letter (தனிக்குறில் taṉikkuṟil) and followed by a hard alphasyllabic letter (வல்லின உயிர்மெய் valliṉa uyirmey). It takes half unit time for pronunciation.

Uyiraḷapeṭai (உயிரளபெடை) and Oṟṟaḷapeṭai (ஒற்றளபெடை) are formed by elongating the duration of pronunciation of a letter to satisfy certain grammatical rules while composing poetry. In Uyiralapetai, the intrinsic vowel of the letter that is elongated is written next to it, to indicate that the letter now is pronounced for 3 units of time.

In Kutriyalukaram, the duration of the short 'u' letters of vallinam category (கு, சு, டு, து, பு, று) is reduced to half units, when the letter is found at the end of the word, preceded by multiple letters or a single nedil(long) letter.

If a word with kutriyalikaram is followed by a word with 'ய'(ya) as the first letter, the u sound is corrupted to i sound and takes a half unit of time for pronunciation.

In Aikarakurukkam and Aukarakurukkam, the duration of the letters ஐ and ஔ are reduced to 1 1/2 units if they are the first letters of the word. If situated elsewhere it is reduced to 1 unit.

In Tamil, a single letter standing alone or multiple letters combined form a word. Tamil is an agglutinative language – words consist of a lexical root to which one or more affixes are attached.

Most Tamil affixes are suffixes. These can be derivational suffixes, which either change the part of speech of the word or its meaning, or inflectional suffixes, which mark categories such as person, number, mood, tense, etc. There is no absolute limit on the length and extent of agglutination, which can lead to long words with a large number of suffixes, which would require several words or a sentence in English. To give an example, the word pōkamuṭiyātavarkaḷukkāka (போகமுடியாதவர்களுக்காக) means "for the sake of those who cannot go", and consists of the following morphemes:

pōka

muṭi

y

āta

var

kaḷ

ukku

āka

go

be possible (impersonal)

epenthetic approximant letter breaks illegal diphthongs

negation (impersonal)

nominalizer he/she who does

plural marker

to

for

Words formed as a result of the agglutinative process are often difficult to translate. Today Translations,^[5] a British translation service, ranks the Tamil word செல்லாதிருப்பவர் (sellātiruppavar, meaning a certain type of truancy) as number 8 in their The Most Untranslatable Word In The World list.

In Tamil, words are classified into four categories namely,

• Nouns Peyarsol
• Verbs Vinaisol
• Particles and Pre-/Postpositions Idaisol
• Adjective and Adverbs Urisol

All categories of nouns are declinable. Verbs are conjugated to indicate person, tense, gender, number and mood. The other two classes are indeclinable.

The nouns stand for the names of objects both animate and inanimate, and abstract concepts. Nouns are the collections of names of animate/inanimate objects (பொருட்பெயர் poruṭpeyar), places (இடப்பெயர் iṭappeyar), concepts of time (காலப்பெயர் kālappeyar), names of limbs of animate/inanimate objects (சினைப்பெயர் ciḷaippeyar), qualitative nouns (பண்புப்பெயர் paṇpuppeyar) and verbal nouns (தொழிற்பெயர் toḷiṟpeyar).

Nouns of place stands for both conceptual names like town, village, heaven and real names like New York, Amsterdam.

Nouns of time includes units of time, names of days of the week, names of months and seasons.

Nouns of quality includes the nature and quality of the abstract and tangible objects. Example: names of tastes, shape, quantity, etc.

The nouns are divided into two main classes based on rationality: The "high class" (உயர்திணை uyartiṇai), and the "lower class" (அஃறிணை aḵṟiṇai).

All the rational beings fall under the category of "high class". Examples could be Adult humans and deities. All the irrational beings and inanimate objects fall under the "lower class". Examples could be animals, birds, plants and things. Since children are considered to be irrational, the word "child" குழந்தை kuḻantai is considered "lower class" or neuter.

Nouns are inflected based on number and grammatical case, of which there are 9: nominative case, accusative case, dative case, instrumental case, sociative case, locative case, ablative case, genitive case, and vocative case. If the plural is used, the noun is inflected by suffixing the noun stem with first the plural marker -kaḷ, and then with the case suffix, if any. Otherwise, if the singular is used, the noun is instead inflected by suffixing either the noun stem with the case suffix, or the oblique stem with the case suffix. An optional euphonic increment -iṉ or -aṉ can occur before the case suffix.

case	suffix
nominative	-∅
accusative	-ai
instrumental	-āl, -(aik) koṇṭu
sociative	-ōṭu, -uṭaṉ
dative	-(uk)ku, -iṉ poruṭṭu, -iṉ nimittam
ablative	-il(ē) iruntu [irrational], -iṭam iruntu [rational], -iṉiṉṟu
genitive	-atu, -uṭaiya
locative	-il(ē) [irrational], -iṭam [rational]
vocative	-ē
benefactive	-(u)kkāka

The nominative case is used for the subject of an intransitive verb, the agent of a transitive verb, the predicate of a nominal sentence, and subject and object complements. It is the base form of the noun with no suffix.

Kumār māṇavaṉ.	"Kumar (is) (a) student."
Kumār māṇavaṉ.	"Kumar becomes (a) student."
Katavu tiṟanatu.	"The door opened."

It can also be used to mark the direct object when it is indefinite and irrational.

The accusative case marks the direct object of a transitive verb. It is marked by the suffix -ai. It is required when the direct object is rational. When used with irrational nouns, the accusative must be used when the direct object is definite. When an irrational direct object is indefinite, the nominative is used instead, unless there is an explicit indefinite determiner present, in which case either the nominative or accusative may be used.

Kumār paiyanai pārtāṉ.	"Kumar sees a/the boy."	(rational direct object, the accusative must be used regardless of definiteness)
Nāṉ eṉ cāviyai tolaittēṉ.	"I lost my key."	(irrational direct object, the possessive pronoun eṉ makes the noun definite, the accusative must be used)
Nāṉ cāviyai tolaittēṉ.	"I lost the key."	(irrational direct object, the accusative shows the noun is definite)
Nāṉ cāvi tolaittēṉ.	"I lost a key."	(irrational direct object, the nominative shows the noun is indefinite)
Nāṉ oru cāvi(yai) tolaittēṉ.	"I lost a key."	(irrational direct object, the determiner oru makes the noun explicitly indefinite, accusative is optional)

The dative case is marked with -ukku, -kku, or -ku. It expresses an indirect object, a goal of motion, a purpose, or an experiencer.

Kumār appāvukku oru paṭattai kāṭiṉāṉ.	"Kumar shows father a picture."	(indirect object)
Kumār ūrukku pōṉāṉ	"Kumar went to a town."	(goal of motion, in this sense restricted to inanimate nouns)
Kumār tāṉ uṭampukku ṭāṉik cāppiṭukiṟāṉ.	"Kumar takes tonic for his health."	(purpose)
Kumārukku oru vīṭu vēnṭum.	"Kumar wants a house."	(experiencer)

The instrumental case is shown with -āl. It marks the instrument, means, source, or reason by which an action occurs.

Kumār kattiyāl paḻattai veṭṭiṉāṉ.

"Kumar cuts the fruit with a knife."

It also marks the agent in passive constructions.

Kumār appāvāl aṭikkappaṭṭāṉ.

"Kumar was beaten by father."

The sociative case is marked with either ōṭu or -uṭaṉ. It shows that the noun it modifies is involved in the action of the sentence.

Kumār taṉ maṉaiviyōṭu vantāṉ.

"Kumar came with his wife."

The locative case is marked with either -il or -iṭam. -il occurs with inanimate nouns and plural animate nouns, while iṭam occurs with animate nouns in both numbers. It shows location.

Kurivi marattil uṭkārkiṟatu.

"The bird is sitting on the tree."

The ablative case is expressed through the suffix -iruntu added onto the locative of a noun. It marks motion away from something.

Kumār marattiliruntu viḻuntāṉ.

"Kumar fell from the tree."

The oblique stem of a noun is used before adding case suffixes, as a modifier in genitive function before a head noun, as the first element of a compound, and before postpositions.

Oblique Stem Formation^[6]

Rule	Tamil		English	Notes
	Nominative	Oblique
0	peyar	peyar-	name	No change. The nominative is identical to the oblique stem. Most Tamil words belong to this group.
1	maram	maratt(u)-	tree	Final -am is replaced with -att(u).
2	pala	palavaṟṟ(u)-	many	Consists of only five words. The suffix -aṟṟ(u) is added to the end of the word.
3	vīṭu	vīṭṭ(u)-	house	The consonant in the last syllable -ṭu or -ṟu is doubled, yielding -ṭṭ(u) or -ṟṟ(u). This applies to all words that end in -ṭu or -ṟu, except those consisting of two short syllables.

The grammatical gender of Tamil nouns corresponds to their natural sex. Nouns in Tamil have two numbers, singular and plural.

Grammatical gender, known as பா pā in Tamil, encompasses both the concepts of gender and number. Masculine and feminine genders are only applicable to "higher class" nouns. Even though the genders of animals are marked in a sentence (e.g.: பெண் நாய் peṇ nāy "female, dog"), grammatically they are handled as a neuter noun. Thus there are five genders in Tamil, namely, masculine singular (ஆண்பால் āṇpāl), feminine singular (பெண்பால் peṇpāl), high-class plural (பலர்பால் palarpāl), lower-class singular (ஒன்றன்பால் oṉṟaṉpāl), lower-class plural (பலவின்பால் palaviṉpāl). These are summarized in the table below.

peyarccol (Name-words)

	rational			irrational
Class	Male	Female	Collective	One	Many
Example: "doer"	ceytavaṉ He who did	ceytavaḷ She who did	ceytavar They who did	ceytatu That which did	ceytavai Those which did

இவன் ivan	he, who is near to the 1st person	near deixis, demonstrative particle
உவன் uvan	he, who is near to the 2nd person	distant deixis, demonstrative particle
அவன் avan	he, who is near to the 3rd person or someone not present	distant deixis, demonstrative particle
எவன் evan	who? (male singular)	interrogative particle

In Tamil, the demonstrative particles are a- (அ), i- (இ), and u- (உ) (archaic and has fallen out of use, except in Sri Lankan dialects). These demonstrative particles display deictic properties. i- (இ) is a near deixis form, which demonstrates the objects around/near the first person, while a- (அ) has distant deixis form, which demonstrates things near the 3rd person. u- (உ) was used to indicate objects near the second person, but has gradually fallen out of use. In modern Tamil i- (இ) indicates objects nearer and a- (அ) indicates objects in a distance. Using these particles demonstrative pronouns are derived. The same set of pronouns is also used as personal pronouns in 3rd person. e.g. avan (he), atu (that object/being), anta (that)

e- (எ) and yā- யா are the two important interrogative particles in Tamil. e- (எ) is used for deriving the interrogative pronouns. e.g. evaṉ (which one, 3rd person singular masculine), enta (which), etaṟku (for what?)

First person plural pronouns in Tamil, distinguish between inclusive and exclusive we. In Tamil, plural terminators are used for honorific addressing. It could be noted in both 2nd and 3rd persons. There are unique personal pronouns available for first and second persons while demonstrative pronouns are used in place of personal pronouns as well.

Pronoun		English Translation	Person / Gender / Number
Nominative	Oblique
நான் nāṉ	என் eṉ	I	1st / neutral / singular
நாம் nām	நம் nam	Inclusive we	1st / neutral / plural
நாங்கள் nāṅkaḷ	எங்கள் eṅkaḷ	Exclusive we	1st / neutral / plural
நீ nī	உன் uṉ	you	2nd / neutral / singular
நீங்கள் nīṅkaḷ	உங்கள் uṅkaḷ	honorific singular you	2nd / neutral / singular
		you	2nd / neutral / plural
அவன் / இவன் avaṉ / ivaṉ		he	3rd / Masculine / singular
அவள் / இவள் avaḷ / ivaḷ		she	3rd / Feminine / singular
அவர் / இவர் avar / ivar		Honorific he/she	3rd / neutral / singular
		they (low class)	3rd / neutral / plural
அவர்கள் / இவர்கள் avarkaḷ/ivarkaḷ		they (high class)	3rd / neutral / plural
அது / இது atu / itu		it (animals and objects)	3rd / neuter / singular
அவை / இவை avai / ivai	அவற்று / இவற்று avaṟṟu / ivaṟṟu	they (animals and objects)	3rd / neuter / plural

Like Tamil nouns, Tamil verbs are also inflected through the use of suffixes. A typical Tamil verb form will have a number of suffixes, which show person, number, mood, tense and voice, as is shown by the following example aḻintukkoṇṭiruntēṉ (அழிந்துக்கொண்டிருந்தேன்) "(I) was being destroyed":

Morphemes	aḻi	-ntu	(k)koṇṭiru	-nt-	-ēn
Functions	root (base)	tense-voice marker	aspect marker	tense marker	person-number-gender marker
	"to be destroyed"	affective voice; past (absolutive)	progressive aspect	past tense	first person, singular

Person and number are indicated by suffixing the oblique case of the relevant pronoun (ēṉ in the above example). The suffixes to indicate tenses and voice are formed from grammatical particles, which are added to the stem. The chart below outlines the most common set of suffixes used to conjugate for person and tense, but different groups of Tamil verbs may use other sets of suffixes or have irregularities.^[7]

Tamil Verb Classes

Class	Root (Example)	Past	Present	Future
I	cey "to do"	-t- (ceyt-)	-kiṟ- (ceykiṟ-)	-v- (ceyv-)
II	mīḷ "to be redeemed"	-ṇṭ- (mīṇṭ-)	-kiṟ- (mīḷkiṟ-)	-v- (mīḷv-)

Person	Singular	Honorary Singular	Plural
1st	-ēṉ		-ōm

¹Class five verbs take -iṟṟu added directly to the root (-iṉ + -tu). In the future, -um is added directly to the root of verbs in Classes I through VIII, whereas -um replaces the -iṟ- in the present stem to form the future of verbs in Classes IX through XIII (and no termination is added afterwards).

²This suffix takes an irregular present in -kiṉṟ-/-kkiṉṟ- before it. The -um future (see directly above) can be used in the plural, as well.

Tamil has three simple tenses – past, present, and future – indicated by simple suffixes, and a series of perfects, indicated by compound suffixes. Mood is implicit in Tamil, and is normally reflected by the same morphemes which mark tense categories. These signal whether the happening spoken of in the verb is unreal, possible, potential, or real. Tamil verbs also mark evidentiality, through the addition of the hearsay clitic ām.^[8]

Tamil has two voices. The first - used in the example above - indicates that the subject of the sentence undergoes or is the object of the action named by the verb stem, and the second indicates that the subject of the sentence directs the action referred to by the verb stem. These voices are not equivalent to the notions of transitivity or causation, or to the active-passive or reflexive-nonreflexive division of voices found in Indo-European languages.

Tamil has no articles. Definiteness and indefiniteness are indicated either by context or by special grammatical devices, such as using the number "one" as an indefinite article. In the first person plural, Tamil makes a distinction between inclusive pronouns that include the listener and exclusive pronouns that do not. Tamil does not distinguish between adjectives and adverbs – both fall under the category uriccol. Conjunctions are called iṭaiccol.

Verb auxiliaries are used to indicate attitude, a grammatical category which shows the state of mind of the speaker, and his attitude about the event spoken of in the verb. Common attitudes include pejorative opinion, antipathy, relief felt at the conclusion of an unpleasant event or period, and unhappiness at or apprehension about the eventual result of a past or continuing event.

Except in poetry, the subject precedes the object, and the verb concludes the sentence. In a standard sentence, therefore, the order is usually subject–object–verb (SOV), but object–subject–verb is also common.

Tamil is a null-subject language. Not all Tamil sentences have subjects, verbs and objects. It is possible to construct valid sentences that have only a verb, such as muṭintuviṭṭatu (முடிந்துவிட்டது, "It is completed"), or only a subject and object, such as atu eṉ vīṭu (அது என் வீடு, "That is my house").

The elements that are present, however, must follow the SOV order. Tamil does not have an equivalent for the existential verb to be; it is included in the translations only to convey the meaning. The negative existential verb, to be not, however, does exist in the form of illai (இல்லை) and goes at the end of the sentence (and does not change with number, gender, or tense). The verb to have in the meaning "to possess" is not translated directly, either. To say "I have a horse" in Tamil, a construction equivalent to "There is a horse to me" or "There exists a horse to me", is used.

Tamil lacks relative pronouns, but their meaning is conveyed by relative participle constructions, built using agglutination. For example, the English sentence "Call the boy who learned the lesson" is said in Tamil like "That-lesson-learned-boy call".
