Etymonline

Word Origin & History

tête-à-tête

1697, "a private meeting," from Fr., lit. "head-to-head," from O.Fr. teste "head" (see tester (2)). The adj., "privately," is recorded from 1728.

to cross one's T's (and dot one's i's) "to be exact" is attested from 1849. Phrase to a T "exactly" is recorded from 1693, though the exact signification is uncertain, despite much speculation. The measuring tool called a T-square is recorded by that name from 1785.

Slang Dictionary

/T/
1. [from LISP terminology for `true'] Yes. Used in reply to a question (particularly one asked using The -P convention). In LISP, the constant T means `true', among other things. Some Lisp hackers use `T' and `NIL' instead of `Yes' and `No' almost reflexively. This sometimes causes misunderstandings. When a waiter or flight attendant asks whether a hacker wants coffee, he may absently respond `T', meaning that he wants coffee; but of course he will be brought a cup of tea instead. Fortunately, most hackers (particularly those who frequent Chinese restaurants) like tea at least as well as coffee -- so it is not that big a problem.
2. See time T (also since time T equals minus infinity).
3. [techspeak] In transaction-processing circles, an abbreviation for the noun `transaction'.
4. [Purdue] Alternate spelling of tee.
5. A dialect of LISP developed at Yale. (There is an intended allusion to NIL, "New Implementation of Lisp", another dialect of Lisp developed for the VAX)

T definition

1. True. A Lisp compiler by Johnathan A. Rees in 1982 at Yale University. T has static scope and is a near-superset of Scheme. Unix source is available. T is written in itself and compiles to efficient native code. Used as the basis for the Yale Haskell system. Maintained by David Kranz .
Latest version: 3.1.
(ftp://ftp.ai.mit.edu/pub/systems/t3.1).
A multiprocessing version of T is available (ftp://masala.lcs.mit.edu/pub/mult).
Runs on Decstation, SPARC, Sun-3, Vax under Unix, Encore, HP, Apollo, Macintosh under A/UX.
E-mail: (bugs). E-mail: .
(1991-11-26)
["The T Manual", Johnathan A. Rees et al, Yale U, 1984].
2. A functional language.
["T: A Simple Reduction Language Based on Combinatory Term Rewriting", Ida et al, Proc of Prog Future Generation Computers, 1988].
3. (lower case) The Lisp atom used to represent "true", among other things. "false" is represented using the same atom as an empty list, nil. This overloading of the basic constants of the language helps to make Lisp write-only code.
4. In transaction-processing circles, an abbreviation for "transaction".
5. (Purdue) An alternative spelling of "tee".
