Tamil has 12 independent vowel letters (uyir ezhuthukkal, உயிர் எழுத்துக்கள் — "life letters") — அ, ஆ, இ, ஈ, உ, ஊ, எ, ஏ, ஐ, ஒ, ஓ, ஔ. Each vowel exists as a standalone letter used at the beginning of a word or syllable, and as a smaller diacritical sign (ukaram) when following a consonant.
A distinctive feature of the Tamil script is the inclusion of both short e (எ) and long ee (ஏ), and both short o (ஒ) and long oo (ஓ) — phonological distinctions written as separate letters, absent from the Devanagari script used for Hindi and Sanskrit.
Tamil uses 18 native consonants (mei ezhuthukkal, மெய் எழுத்துக்கள் — "body letters") plus 5 Grantha consonants (ஜ, ஶ, ஷ, ஸ, ஹ) used in Sanskrit and English loanwords. Each consonant carries an inherent short /a/ vowel, modified by vowel signs or suppressed by the pulli (், virama).
The Tamil consonant system includes three sounds found in no other major world language: the unique retroflex approximant ழ (zha, /ɻ/) — heard in the very word "தமிழ்" (Tamil) — the distinctive alveolar trill ற (rra), and the retroflex lateral ள (lla, /ɭ/).
Tamil uses 11 vowel signs (ukara ezhuthukkal) — diacritical marks attached to consonants to indicate the following vowel, replacing the inherent /a/. Three vowel signs (ொ, ோ, ௌ) are two-part signs that wrap around the consonant, written partly before and partly after.
The pulli (், virama) suppresses the inherent vowel to produce a "pure" consonant sound. The unique aytham (ஃ) — resembling three dots — represents a light aspirated sound used before certain consonants and in some loanwords. These marks are essential for reading and writing accurate Tamil.
Tamil traditionally uses Tamil numerals (௦–௯) in formal, literary, and classical contexts. These digits are encoded in the Tamil Unicode block (U+0BE6–U+0BEF) and follow the decimal positional system.
In everyday use, modern Tamil speakers also use Arabic-Indic numerals (0–9). Tamil number words are distinct — for example, "one" is oṉṟu, "two" is iraṇḍu, and "three" is mūṉṟu in Tamil.
Tamil uses the Brahmic danda (।) as a traditional sentence-ending mark and the double danda (॥) at the end of verses in literary and religious texts.
Modern Tamil writing in newspapers and digital media commonly uses standard Latin punctuation marks (full stop, comma, question mark) alongside or instead of traditional Brahmic marks. Tamil also uses the sacred Tamil Om (ௐ) in religious contexts.
The Tamil Unicode block (U+0B80–U+0BFF) includes two additional signs beyond the main vowel and consonant inventory. The Tamil Sign Anusvara (ஂ, U+0B82) is a combining nasalising mark used in Tamil renditions of Sanskrit texts and Grantha passages — it is distinct from the standalone Aytham (ஃ, U+0B83), which is a native Tamil letter already part of the Tamil alphabet.
The Au Length Mark (ௗ, U+0BD7) is the second component of the two-part Tamil au vowel sign ௌ (U+0BCC): the au matra is encoded as a pre-base element (U+0BC6) placed before the consonant plus this post-base length mark placed after it. It is encoded separately for precise scholarly and digital text-processing contexts.
Beyond the ten Tamil digit symbols (௦–௯), the Tamil Unicode block includes three traditional higher-order numeral symbols: Ten (௰, U+0BF0), One Hundred (௱, U+0BF1), and One Thousand (௲, U+0BF2). These symbols appear in classical Tamil manuscripts, temple inscriptions, copper plate grants, and traditional accounting records, where large numbers were written by combining these symbols with the digit numerals.
For example, the number 2,500 would classically be written as ௨௲௫௱ (2 × thousand + 5 × hundred). These higher numeral symbols are found in Sangam literature, medieval Tamil inscriptions, and pre-modern palm-leaf manuscripts, but are not used in modern everyday Tamil writing, which uses Arabic numerals.
The Tamil Unicode block includes three traditional calendrical symbols used in Tamil almanacs (பஞ்சாங்கம், panchangam) and traditional calendrical records: Day Sign (௳, U+0BF3), Month Sign (௴, U+0BF4), and Year Sign (௵, U+0BF5). These symbols appear as column or section labels in panchangam tables, astronomical records, and inscriptions where dates are given in the Tamil calendar system.
Tamil uses its own 60-year cycle calendar (the Prabhava–Vibhava cycle) alongside the Hindu solar calendar. The Tamil calendar month names — Chittirai, Vaikasi, Aani, Aadi, Aavani, Purattasi, Aippasi, Karthigai, Margazhi, Thai, Maasi, Panguni — are distinct from both Gregorian and Sanskrit month names. These calendrical symbols mark the relevant column types in traditional printed almanacs.
The Tamil Unicode block includes five clerical and commercial symbols used in traditional Tamil bookkeeping and official records. The Debit Sign (௶, U+0BF6) and Credit Sign (௷, U+0BF7) are used in Tamil double-entry ledgers and accounting manuscripts to mark expenditure and income respectively. The As Above Sign (௸, U+0BF8) functions as a ditto mark — placed in a ledger column to indicate the same entry as the line above.
The Tamil Rupee Sign (௹, U+0BF9) is the Tamil script symbol for the Indian Rupee, used in traditional Tamil printed financial documents before the pan-Indian ₹ symbol (U+20B9) was adopted in 2010. The Number Sign (௺, U+0BFA) is placed before a numeral in lists and records to indicate a count or serial number — analogous to the "#" symbol in English typography. All five symbols are found in historic Tamil commercial manuscripts and early Tamil printing.
The Tamil Uyirmei Ezhuthukkal (உயிர்மெய் எழுத்துக்கள்) — literally "vowel-consonant letters" (uyir = life/vowel, mei = body/consonant) — shows all 23 consonants combined with all 13 vowel forms (12 vowels + the pulli), producing 299 syllables in total. Each cell is a standalone Tamil syllable. [1]
Read by row (consonant) and column (vowel): scroll right to see all 13 vowel forms. The traditional Tamil uyirmei count is 18 consonants × 12 vowels = 216; this chart extends it to include 5 Grantha consonants used in loanwords. [5]

A complete view of all 37 Tamil letters — 12 vowels (uyir), 18 native consonants, 5 Grantha consonants, and the special aytham (ஃ) — in the traditional Tamil script alphabetical order for quick reference.
The Tamil alphabet is called Aricuvadi (அரிச்சுவடி) — the traditional order of letters used in Tamil learning. Vowels come first, then the consonants in their varga groups, followed by the Grantha consonants.
