T \T\ (t[=e]),
the twentieth letter of the English alphabet, is a nonvocal
consonant. With the letter h it forms the digraph th, which
has two distinct sounds, as in thin, then. See Guide to
Pronunciation, [sect][sect]262-264, and also [sect][sect]153,
156, 169, 172, 176, 178-180.
[1913 Webster] The letter derives its name and form from the
Latin, the form of the Latin letter being further derived
through the Greek from the Ph[oe]nician. The ultimate origin
is probably Egyptian. It is etymologically most nearly
related to d, s, th; as in tug, duke; two, dual, L. duo;
resin, L. resina, Gr. "rhti`nh, tent, tense, a., tenuous,
thin; nostril, thrill. See D, S.
