{{Latin letter info|t}}

'''T''', or '''t''', is the twentieth [[Letter (alphabet)|letter]] of the [[Latin alphabet]], used in the [[English alphabet|modern English alphabet]], the alphabets of other western European languages and others worldwide. Its name in English is [[English alphabet#Letter names|''tee'']] (pronounced {{IPAc-en|'|t|iː|audio=LL-Q1860 (eng)-Flame, not lame-T.wav}}), plural ''tees''.<ref>"T", ''Oxford English Dictionary,'' 2nd edition (1989); ''Merriam-Webster's Third New International Dictionary of the English Language, Unabridged'' (1993); "tee", ''op. cit''.</ref>

It is derived from the Semitic [[Taw]] 𐤕 of the [[Phoenician alphabet|Phoenician]] and [[Paleo-Hebrew]] script ([[Aramaic alphabet|Aramaic]] and [[Hebrew alphabet|Hebrew]] Taw ת/𐡕/[[File:Taw.svg|class=skin-invert-image|10 px]], [[Syriac alphabet|Syriac]] Taw ܬ, and [[Arabic script|Arabic]] ت [[Tāʼ]]) via the Greek letter [[tau|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 commonly used letter in English-language texts.<ref>{{cite web|url=http://pages.central.edu/emp/LintonT/classes/spring01/cryptography/letterfreq.html |title=Relative Frequencies of Letters in General English Plain text |last=Lewand |first=Robert |work=Cryptographical Mathematics |publisher=[[Central College (Pella, Iowa)|Central College]] |access-date=2008-06-25 |url-status=dead |archive-url=https://web.archive.org/web/20080708193159/http://pages.central.edu/emp/LintonT/classes/spring01/cryptography/letterfreq.html |archive-date=2008-07-08 }}</ref>

''[[Taw]]'' was the last letter of the Western [[Semitic alphabets|Semitic]] and [[Hebrew alphabet]]s. The sound value of Semitic ''Taw'', the [[Greek alphabet]] Tαυ (''Tau''), [[Old Italic alphabet|Old Italic]] and Latin T has remained fairly constant, representing {{IPAblink|t}} in each of these, and it has also kept its original basic shape in most of these alphabets.

===English===
In English, {{angbr|t}} usually denotes the [[voiceless alveolar plosive]] ([[help:IPA|International Phonetic Alphabet]] and [[X-SAMPA]]: {{IPAslink|t}}), as in ''tart'', ''tee'', or ''ties'', often with [[Aspirated consonant|aspiration]] at the beginnings of words or before [[Stress (linguistics)|stressed]] vowels. The letter {{angbr|t}} corresponds to the affricate {{IPA|/t͡ʃ/}} in some words as a result of [[Phonological history of English consonant clusters#Yod-coalescence|yod-coalescence]] (for example, in words ending in -"ture", such as ''future'').

A common [[Digraph (orthography)|digraph]] is {{angbr|th}}, which usually represents a [[dental fricative]], but occasionally represents {{IPA|/t/}} (as in ''Thomas'' and ''thyme''). The digraph {{angbr|ti}} often corresponds to the sound {{IPA|/ʃ/}} (a [[voiceless palato-alveolar sibilant]]) word-medially when followed by a vowel, as in ''nation'', ''ratio'', ''negotiation'', and ''Croatia''.

In a few words of modern French origin, the letter T is silent at the end of a word; these include ''croquet'' and ''debut''.

===Other languages===
In the [[orthographies]] of other languages, {{angbr|t}} is often used for {{IPA|/t/}}, the [[voiceless dental plosive]] {{IPA|/t̪/}}, or similar sounds.

===Other systems===
In the [[International Phonetic Alphabet]], {{angbr IPA|t}} denotes the [[voiceless alveolar plosive]].
