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 //), plural tees. It is derived from the Semitic letters taw (ת, ܬ, ت) via the Greek letter τ (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.
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
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).
