Tamil Grammar (Ilakkanam) — Study Notes for TNPSC Group IV
Overview
Tamil Grammar, known as Ilakkanam (இலக்கணம்), forms the foundation of the General Tamil paper in TNPSC Group IV examination. This section tests your understanding of the classical grammatical structure of Tamil as codified in ancient texts, particularly Tholkappiyam and Nannool.
The TNPSC Group IV exam assesses Tamil grammar at SSLC standard, covering six core divisions: Eluthu (letters), Sol (words), Porul (meaning/themes), Yappu (prosody), Ani (figures of speech), and Punarchi (sandhi/word combination). Mastery of these fundamentals is essential because grammar questions appear directly and also help in comprehending prose passages and literature-based questions.
Students must focus on understanding the classification systems, memorising key terminology, and recognising grammatical forms in context. The exam typically tests definitions, classifications, examples, and application of rules rather than abstract theoretical knowledge.
Key Concepts
- Eluthu (எழுத்து): Tamil has 247 letters — 12 vowels (uyir), 18 consonants (mei), 216 compound letters (uyirmei), and 1 special character (aytham ஃ). This 12+18+216+1 = 247 classification is fundamental.
- Sol (சொல்): Words are classified by origin into four types — Iyarcol (native Tamil), Thisaicol (regional/dialectal), Vadacol (Sanskrit borrowings), and Thiricol (corrupted/changed words).
- Sol by Grammar Function: Words are also classified as Peyarcol (noun), Vinaisol (verb), Idaisol (particle/conjunction), and Uricol (adjective/adverb with emphasis).
- Porul (பொருள்): Classical Tamil literature follows Aham (love/inner themes) and Puram (war/heroism/outer themes). Aham has five thinais (landscapes) each associated with specific emotions.
- Yappu (யாப்பு): Tamil prosody studies the structure of verse — asai (syllable unit), seer (metrical foot), thalai (linkage), adi (line), and thodai (rhyme/ornament).
- Ani (அணி): Figures of speech beautify language. Key types include Uvamai (simile), Uruvagam (metaphor), Tharpugazhchi (self-praise for effect), and Pirandiyal (contrast/irony).
- Punarchi (புணர்ச்சி): Sandhi rules govern how letters and words join. The two main types are Iyalpunarchi (natural joining) and Pugaipunarchi (joining with an additional letter inserted).
Formulas / Key Facts
| Category | Classification | Count/Details |
|---|---|---|
| Uyir eluthu (vowels) | அ, ஆ, இ, ஈ, உ, ஊ, எ, ஏ, ஐ, ஒ, ஓ, ஔ | 12 letters |
| Mei eluthu (consonants) | க், ங், ச், ஞ், ட், ண், த், ந், ப், ம், ய், ர், ல், வ், ழ், ள், ற், ன் | 18 letters |
| Uyirmei (compound) | Each mei + each uyir | 18 × 12 = 216 |
| Kuril (short vowels) | அ, இ, உ, எ, ஒ | 5 vowels |
| Nedil (long vowels) | ஆ, ஈ, ஊ, ஏ, ஐ, ஓ, ஔ | 7 vowels |
| Vallinam (hard consonants) | க், ச், ட், த், ப், ற் | 6 letters |
| Mellinam (soft consonants) | ங், ஞ், ண், ந், ம், ன் | 6 letters |
| Idaiyinam (medium consonants) | ய், ர், ல், வ், ழ், ள் | 6 letters |
Five Thinais of Aham Poetry:
- Kurinji (குறிஞ்சி) — Mountain — Union of lovers
- Mullai (முல்லை) — Forest — Patient waiting
- Marutham (மருதம்) — Agricultural land — Sulking/quarrel
- Neithal (நெய்தல்) — Seashore — Pining/separation
- Paalai (பாலை) — Desert — Elopement/hardship
Yappu Structure (smallest to largest): Asai → Seer → Adi → Thodai → Pa
Worked Examples
Example 1: Letter Classification Question: Classify the letter "கா" by type.
Solution:
- "கா" is formed by combining க் (mei) + ஆ (uyir)
- Therefore, it is an Uyirmei eluthu (compound letter)
- Since ஆ is a nedil (long vowel), "கா" is also called a nedil uyirmei
Example 2: Word Classification Question: Identify the sol vagaigal (word types) — பூ, ராஜா, பேச்சு
Solution:
- பூ (flower) — Pure Tamil word → Iyarcol
- ராஜா (king) — Borrowed from Sanskrit → Vadacol
- பேச்சு (speech/talk) — Colloquial variation of பேசுதல் → Thiricol
Example 3: Identifying Ani Question: "முகம் தாமரை போன்றது" — What figure of speech is this?
Solution:
- Translation: "The face is like a lotus"
- Comparison word "போன்றது" (like) is explicitly present
- When comparison is made using linking words (போல், போன்ற, நிகர்) → Uvamai Ani (simile)
- If it were "முகத்தாமரை" (face-lotus as one word), it would be Uruvagam (metaphor)
Common Mistakes
- Confusing Vallinam count: Students sometimes include ற் with idaiyinam because it sounds soft. → Remember: ற் is vallinam. The hard consonants are க், ச், ட், த், ப், ற் — all six involve a stop sound.
- Mixing Iyarcol and Thiricol: Both are Tamil words, but Iyarcol is the standard/classical form while Thiricol is a corrupted/dialectal variation. → If the word appears in Sangam literature in that form, it is likely Iyarcol.
- Forgetting Aytham: When asked total Tamil letters, students write 246 (12+18+216). → Always add 1 for Aytham (ஃ) = 247 total.
- Confusing Kuril and Nedil in diphthongs: ஐ and ஔ are considered nedil even though they are diphthongs. → Memorise: 5 kuril (அ, இ, உ, எ, ஒ) and 7 nedil (ஆ, ஈ, ஊ, ஏ, ஐ, ஓ, ஔ).
- Porul: Mixing Aham thinais: Students confuse Mullai (waiting) with Neithal (pining). → Mullai is hopeful waiting in forest; Neithal is sorrowful pining by the sea.
Quick Reference
- Total Tamil letters: 12 + 18 + 216 + 1 = 247
- Mei classification: Vallinam (6) + Mellinam (6) + Idaiyinam (6) = 18
- Sol by origin: Iyarcol, Thisaicol, Vadacol, Thiricol
- Sol by grammar: Peyarcol, Vinaisol, Idaisol, Uricol
- Aham thinais: Kurinji-Mullai-Marutham-Neithal-Paalai (memorise: KuMu MaNe Pa)
- Uvamai vs Uruvagam: Comparison word present = Uvamai; direct equation = Uruvagam
