Ṭa (Indic)

Phonemic representation:	/ʈ/
IAST transliteration:	tta
ISCII code point:	BB (187)

Tta is the eleventh consonant of Indic abugidas. In modern Indic scripts, ṭa is derived from the Brahmi letter after having gone through the Gupta letter .

Āryabhaṭa numeration

Aryabhata used Devanagari letters for numbers, very similar to the Greek numerals, even after the invention of Indian numerals. The values of the different forms of ट are:^[1]

ट [ʈə] = 9 (९)
टि [ʈɪ] = 900 (९००)
टु [ʈʊ] = 90,000 (९० ०००)
टृ [ʈri] = 9,000,000 (९० ०० ०००)
टे [ʈe] = 9×10¹⁰ (९०^१०)
टै [ʈɛː] = 9×10¹² (९०^१२)
टो [ʈoː] = 9×10¹⁴ (९०^१४)
टौ [ʈɔː] = 9×10¹⁶ (९०^१६)

Devanagari script

Ṭa (ट) is the eleventh consonant of the Devanagari abugida. In many languages, ट is pronounced as [ʈə] or [ʈ] when appropriate. In Marathi, ट is sometimes pronounced as [tə] or [t] in addition to [ʈə] or [ʈ]. ^[2] Letters that derive from it are the Gujarati letter ટ and the Modi letter 𑘘.

Bengali script

ট is used as a basic consonant character in all of the major Bengali script orthographies, including Bengali and Assamese.

Gujarati script

Ṭa (ટ) is the eleventh consonant of the Gujarati script. It is possibly derived from a variant of 16th century Devanagari letter ṭa (ट) with the top bar (shiro rekha) removed.

Thai script

To Patak (ฏ) is the fifteenth letter of the Thai script. It falls under the low class of Thai consonants. In IPA, to patak is pronounced as [t] at the beginning of a syllable and may not be used to close a syllable. The 21st letter of the alphabet, to tao (ต), is also named to and falls under the middle class of Thai consonants. Thai consonants do not form conjunct ligatures, and use the pinthu—an explicit virama with a dot shape—to indicate bare consonants. In the acrophony of the Thai script, patak (ปฏัก) means ‘skewers’. To Patak corresponds to the Sanskrit character ‘ट’.
