T (tē), 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, §§262-264, and also §§153, 156, 169, 172,
176, 178-180.
The letter derives its name and form
from the Latin, the form of the Latin letter being further derived through the Greek from the Phœnician. 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.
