T square
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}. [1913 Webster]
