Eluttu Ilakkanam — Tamil Letters

Overview

Eluttu Ilakkanam (எழுத்து இலக்கணம்) is the foundational branch of Tamil grammar that deals with the classification, properties and rules governing Tamil letters. For TN TET Language I, this topic forms the bedrock upon which all other grammar sections build. A strong grasp of Tamil phonology and script structure is essential for teaching primary students how to read and write.

This topic directly tests your knowledge of vowels (uyir eluttu), consonants (mey eluttu) and combined characters (uyirmey eluttu). Questions typically appear as direct factual recalls—counting letters, identifying categories, or applying rules from Tolkappiyam. Expect 2–4 questions in Paper I and Paper II from this area. Mastering the systematic classification and the concept of kuril/nedil (short/long) distinction is non-negotiable.

The authoritative source for Tamil letter grammar is Tolkappiyam, the oldest surviving Tamil grammar text. Most exam questions align with the traditional 247-letter system described in this classical work.

Key Concepts

• **Total Tamil letters = 247** — This comprises 12 vowels + 18 consonants + 216 combined letters + 1 special character (ayutha eluttu).

• **Uyir Eluttu (உயிர் எழுத்து) = 12 vowels** — These are "life letters" that can be pronounced independently. They are the soul of syllables.

• **Mey Eluttu (மெய் எழுத்து) = 18 consonants** — These are "body letters" that require a vowel to produce sound. They carry the pulli (்) marker in pure form.

• **Uyirmey Eluttu (உயிர்மெய் எழுத்து) = 216 combined letters** — Formed by combining each of 18 consonants with each of 12 vowels (18 × 12 = 216).

• **Ayutha Eluttu (ஆய்த எழுத்து) = ஃ** — A unique special character, neither vowel nor consonant, used only between two kuril letters. Also called "thanittru eluttu" (standalone letter).

• **Kuril (குறில்) vs Nedil (நெடில்)** — Kuril are short vowels (1 maattirai), Nedil are long vowels (2 maattirai). This distinction is fundamental to prosody and pronunciation.

• **Maattirai (மாத்திரை)** — The unit of time measurement for pronouncing letters. It is the duration taken to snap a finger or blink an eye.
