Tamil grammar, step by step

Tamil verbs always come at the end of the sentence. The ending encodes person, number, and social class of the subject all at once.

Tamil is strictly verb-final (Subject–Object–Verb). Adjectives and descriptive clauses also come before the noun they modify, not after.

Tamil divides all nouns into two classes: rational (உயர்திணை, uyartiṇai — humans and deities) and irrational (அஃறிணை, aḵṟiṇai — animals, objects, concepts). This distinction affects pronouns and verb endings.

Tamil marks grammatical relationships with suffixes added directly onto the noun. Each suffix encodes a role — object, recipient, location, and so on — replacing what many languages express with prepositions.

Past tense is formed by inserting a past-tense marker between the verb stem and the personal suffix. The marker varies by verb class — the most common markers are -இன்- and -ட்ட்-.

Future tense uses the marker -வ்- (v) inserted between stem and personal suffix. The three-way contrast — present, past, future — is expressed entirely through the middle marker.

Tamil negates verbs by using -வில்லை attached after the infinitive stem (for present/past), or இல்லை as a negative copula. The negation comes at the very end of the verb phrase, not before it.

Yes/no questions are formed by adding the particle ஆ (ā) to the end of the sentence. Question words like என்ன (what) and யார் (who) stay in the position where the answer would go.

Adjectives in Tamil always precede the noun and never change form — there is no agreement for class, number, or grammatical role. The same adjective form works for rational and irrational nouns alike.

The infinitive (verb stem + -அ) is a non-finite base form: it carries no tense or person. Modal verbs like முடியும் (can) and வேண்டும் (must/want) follow the infinitive.

Tamil converts any verb into a noun using -வது (-vatu): பேசுவது means "the act of speaking" or simply "speaking." This verbal noun can function as the subject, object, or complement of a sentence.

Tamil forms relative clauses by converting the verb into a participial form that comes before the noun. Present, past, and future participles each have their own form. No relative pronoun is needed.

என்று (eṉṟu, literally "saying that") is a quotative particle that follows a complete clause and turns it into a subordinate clause. It works for direct speech, indirect speech, and verbs of thinking and knowing.

Tamil has two key aspect constructions: the progressive (verb + கொண்டிருக்கிறேன், "am in the process of") shows an ongoing action; the completive (verb + விட்டேன், "did and finished") shows an action completed with finality.

Tamil's patterns combine naturally: SOV order, stacked suffixes for tense and agreement, verbal nouns as subjects, and negation at the very end — all working together in a single sentence.
