T, 20th letter of the alphabet. It corresponds to the Greek tau. It represents the unvoiced dental or, as in English, the alveolar stop. The diagraph th represents the characteristic English interdental fricative, voiced in this, voiceless in thing. For modern misapprehensions concerning older signs for the fricative, see the letter Y.
