| | Definition: | | \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. 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}.

T is written in itself and compiles to efficient native code. Used as the basis for the Yale Haskell system. Maintained by David Kranz <[email protected]>. Current version: 3.1. A multiprocessing version of T is available . Runs on Decstation, SPARC, Sun-3, Vax under Unix, Encore, HP, Apollo, Macintosh under A/UX. E-mail: <[email protected]> (bugs).

["T: A Simple Reduction Language Based on Combinatory Term Rewriting", Ida et al, Proc of Prog Future Generation Computers, 1988]. 3.
