T

T or t is the 20th letter in the modern English alphabet and the ISO basic Latin alphabet. Its name in English is tee (pronounced /ˈt/), plural tees.[1] It is derived from the Semitic letter taw via the Greek letter tau. In English, it is most commonly used to represent the voiceless alveolar plosive, a sound it also denotes in the International Phonetic Alphabet. It is the most commonly used consonant and the second most common letter in English-language texts.[2]

Tau

Taw was the last letter of the Western Semitic and Hebrew alphabets. The sound value of Semitic Taw, Greek alphabet Tαυ (Tau), Old Italic and Latin T has remained fairly constant, representing [t] in each of these; and it has also kept its original basic shape in most of these alphabets.

Use in writing systems

English

In English, t usually denotes the voiceless alveolar plosive (International Phonetic Alphabet and X-SAMPA: /t/), as in tart, tee, or ties, often with aspiration at the beginnings of words or before stressed vowels.

The digraph ti often corresponds to the sound /ʃ/ (a voiceless palato-alveolar sibilant) word-medially when followed by a vowel, as in nation, ratio, negotiation, and Croatia.

The letter t corresponds to the affricate /t͡ʃ/ in some words as a result of yod-coalescence (for example, in words ending in "-ture", such as future).

A common digraph is th, which usually represents a dental fricative, but occasionally represents /t/ (as in Thomas and thyme.)

Other languages

In the orthographies of other languages, t is often used for /t/, the voiceless dental plosive /t̪/ or similar sounds.

Other systems

In the International Phonetic Alphabet, t denotes the voiceless alveolar plosive.
