The Tamil script (தமிழ் அரிச்சுவடி Tamiḻ ariccuvaṭi [tamiɻ ˈaɾitːɕuʋaɽi]) is an abugida script that is used by Tamils and Tamil speakers in India, Sri Lanka, Malaysia, Singapore, Indonesia and elsewhere to write the Tamil language.^[5] It is one of the official scripts of the Indian Republic. Certain minority languages such as Saurashtra, Badaga, Irula and Paniya are also written in the Tamil script.^[6]

Tamil is written in a non-Latin script. Tamil text used in this article is transliterated into the Latin script according to the ISO 15919 standard.

The Tamil script has 12 vowels (உயிரெழுத்து, uyireḻuttu, "soul-letters"), 18 consonants (மெய்யெழுத்து, meyyeḻuttu, "body-letters") and one special character, the ஃ (ஆய்த எழுத்து, āytha eḻuttu). ஃ is called "அக்கு", akku and is classified in Tamil orthography as being neither a consonant nor a vowel.^[7] However, it is listed at the end of the vowel set. The script is syllabic, not alphabetic. The complete script, therefore, consists of the 31 letters in their independent forms and an additional 216 combinatory letters, for a total of 247 (12+18+216+1) combinations (உயிர்மெய்யெழுத்து, uyirmeyyeḻuttu, "soul-body-letters") of a consonant and a vowel, a mute consonant or a vowel alone. The combinatory letters are formed by adding a vowel marker to the consonant. Some vowels require the basic shape of the consonant to be altered in a way that is specific to that vowel. Others are written by adding a vowel-specific suffix to the consonant, yet others a prefix and still other vowels require adding both a prefix and a suffix to the consonant. In every case, the vowel marker is different from the standalone character for the vowel. ^{[citation needed]}

The Tamil script is written from left to right.

The Tamil script, like the other Brahmic scripts, is thought to have evolved from the original Brahmi script.^[8] The earliest inscriptions which are accepted examples of Tamil writing date to the Ashokan period. The script used by such inscriptions is commonly known as the Tamil-Brahmi or "Tamili script" and differs in many ways from standard Ashokan Brahmi. For example, early Tamil-Brahmi, unlike Ashokan Brahmi, had a system to distinguish between pure consonants (m, in this example) and consonants with an inherent vowel (ma, in this example). In addition, according to Iravatham Mahadevan, early Tamil Brahmi used slightly different vowel markers, had extra characters to represent letters not found in Sanskrit and omitted letters for sounds not present in Tamil such as voiced consonants and aspirates.^[8] Inscriptions from the 2nd century use a later form of Tamil-Brahmi, which is substantially similar to the writing system described in the Tolkāppiyam, an ancient Tamil grammar. Most notably, they used the puḷḷi to suppress the inherent vowel.^[9] The Tamil letters thereafter evolved towards a more rounded form and by the 5th or 6th century, they had reached a form called the early vaṭṭeḻuttu.^[10]

The modern Tamil script does not, however, descend from that script.^[11] In the 4th century,^[12] the Pallava dynasty created a new script called Pallava script for Tamil and the Grantha alphabet evolved from it, adding the Vaṭṭeḻuttu alphabet for sounds not found to write Sanskrit.^[4] Parallel to Grantha alphabet a new script (Chola-Pallava script, which evolved to modern Tamil script) again emerged in Pallava and Chola territories resembling the same glyph development like Grantha, however, heavily reduced in its shapes and not overtaking non-native Tamil sounds. By the 8th century, the new scripts supplanted Vaṭṭeḻuttu in the Pallava and Chola kingdoms which lay in the north portion of the Tamil-speaking region. However, Vaṭṭeḻuttu continued to be used in the southern portion of the Tamil-speaking region, in the Chera and Pandyan kingdoms until the 11th century, when the Pandyan kingdom was conquered by the Cholas who inherited while being feudatory of Pallavas for a short time.^[3][4]

With the fall of Pallava kingdom, the Chola dynasty pushed the Chola-Pallava script as the de facto script. Over the next few centuries, the Chola-Pallava script evolved into the modern Tamil script. The Grantha and its parent script influenced the Tamil script notably. The use of palm leaves as the primary medium for writing led to changes in the script. The scribe had to be careful not to pierce the leaves with the stylus while writing because a leaf with a hole was more likely to tear and decay faster. As a result, the use of the puḷḷi to distinguish pure consonants became rare, with pure consonants usually being written as if the inherent vowel were present. Similarly, the vowel marker (ஃ) called: Tamil: குற்றியலுகரம், romanized: kuṟṟiyal-ukaram, lit. 'short 'u'-sound', a half-rounded u which occurs at the end of some words and in the medial position in certain compound words, marking a shortened u sound, also fell out of use and was replaced by the marker for the simple u (ு). The puḷḷi (ஂ) did not fully reappear until the introduction of printing, but the marker kuṟṟiyal-ukaram (ஃ) never came back for this purpose into use although its usage is retained in certain grammatical conceptual words whereas the sound itself still exists and plays an important role in Tamil prosody.

The forms of some of the letters were simplified in the 19th century to make the script easier to typeset. In the 20th century, the script was simplified even further in a series of reforms, which regularised the vowel markers used with consonants by eliminating special markers and most irregular forms.

The Tamil script differs from other Brahmi-derived scripts in a number of ways. Unlike every other Brahmic script, it does not regularly represent voiced or aspirated stop consonants as these are not phonemes of the Tamil language even though voiced and fricative allophones of stops do appear in spoken Tamil. Thus the character க் k, for example, represents /k/ but can also be pronounced [g] or [x] based on the rules of Tamil phonology. A separate set of characters appears for these sounds when the Tamil script is used to write Sanskrit or other languages.

Also unlike other Brahmi scripts, the Tamil script rarely uses typographic ligatures to represent conjunct consonants, which are far less frequent in Tamil than in other Indian languages. Where they occur, conjunct consonants are written by writing the character for the first consonant, adding the puḷḷi to suppress its inherent vowel, and then writing the character for the second consonant. There are a few exceptions, namely க்ஷ kṣa and ஶ்ரீ śrī.

ISO 15919 is an international standard for the transliteration of Tamil and other Indic scripts into Latin characters. It uses diacritics to map the much larger set of Brahmic consonants and vowels to the Latin script.

Apart from the usual numerals (from 0 to 9), Tamil also has numerals for 10, 100 and 1000. Symbols for fraction and other number-based concepts can also be found.^[19]

Tamil script was added to the Unicode Standard in October 1991 with the release of version 1.0.0. The Unicode block for Tamil is U+0B80–U+0BFF. Grey areas indicate non-assigned code points. Most of the non-assigned code points are designated reserved because they are in the same relative position as characters assigned in other South Asian script blocks that correspond to phonemes that don't exist in the Tamil script.

Efforts to unify the Grantha script with Tamil have been made;^[16][20] however the proposals triggered discontent by some.^[21][22] Eventually, considering the sensitivity involved, it was determined that the two scripts should be encoded independently, except for the numerals.^[23]

Proposals to encode characters used for fractional values in traditional accounting practices were submitted.^[24] Although discouraged by the ICTA of Sri Lanka,^[25] the proposal was recognized by the Government of Tamil Nadu^[26] and were added to the Unicode Standard in March 2019 with the release of version 12.0. The Unicode block for Tamil Supplement is U+11FC0–U+11FFF:
