9 Grammatical Pitfalls
c.1200, "fixed amount, measure, portion," from Old French piece "piece, bit portion; item; coin" (12c.), from Vulgar Latin *pettia, probably from Gaulish *pettsi (cf. Welsh peth "thing," Breton pez "piece, a little"), perhaps from an Old Celtic base *kwezd-i-, from PIE root *kwezd- "a part, piece" (cf. Russian chast' "part"). Related: Pieces.
Sense of "portable firearm" first recorded 1580s; that of "chessman" is from 1560s. Meaning "person regarded as a sex object" is first recorded 1785 (cf. piece of ass, human beings colloquially called piece of flesh from 1590s; cf. also Latin scortum "bimbo, anyone available for a price," literally "skin"). Meaning "a portion of a distance" is from 1610s; that of "literary composition" dates from 1530s. Piece of (one's) mind is from 1570s. Piece of work "remarkable person" echoes Hamlet. Piece as "a coin" is attested in English from 1570s, hence Piece of eight, old name for the Spanish dollar (c.1600) of the value of 8 reals.
PIECE. A wench. A damned good or bad piece; a girl who is more or less active and skilful in the amorous congress. Hence the (Cambridge) toast, may we never have a PIECE (peace) that will injure the constitution. ["Dictionary of Buckish Slang, University Wit and Pickpocket Eloquence," London, 1811]
"to mend by adding pieces," late 14c., from piece (n.). Sense of "to join, unite, put together" is from late 15c. Related: Pieced; piecing.
[second sense, US underworld use since about 1930]
(1) of silver. In Ps. 68:30 denotes "fragments," and not properly money. In 1 Sam. 2:36 (Heb. agorah), properly a "small sum" as wages, weighed rather than coined. Josh. 24:32 (Heb. kesitah, q.v.), supposed by some to have been a piece of money bearing the figure of a lamb, but rather simply a certain amount. (Comp. Gen. 33:19). (2.) The word pieces is omitted in many passages, as Gen. 20:16; 37:28; 45:22, etc. The passage in Zech. 11:12, 13 is quoted in the Gospel (Matt. 26:15), and from this we know that the word to be supplied is "shekels." In all these omissions we may thus warrantably supply this word. (3.) The "piece of money" mentioned in Matt. 17:27 is a stater=a Hebrew shekel, or four Greek drachmae; and that in Luke 15:8, 9, Act 19:19, a Greek drachma=a denarius. (See PENNY.)
