1560s, "a molded projection which crowns the part to which it is affixed," from French corniche (16c.) or directly from Italian cornice "ornamental molding along a wall," perhaps from Latin coronis "curved line, flourish in writing," from Greek koronis "curved object" (see crown). Perhaps influenced by (or even from) Latin cornicem, accusative of cornix "crow" (compare corbel). Sense of "ornamental molding running round the walls of a room just below the ceiling" is from 1660s.
1640s, of hair, "turning white;" 1680s, of glass, "having a rough and unpolished surface;" 1734 in cookery, "covered with something (sugar, icing) resembling frost," past-participle adjective from frost (v.).
late 14c., apartment in the royal palace at Westminster in which members of the king's council sat to exercise jurisdiction 14-15c., it evolved 15c. into a court of criminal jurisdiction, infamous under James I and Charles I for arbitrary and oppressive proceedings. Abolished 1641. Supposedly so called because gilt stars had been painted on the ceiling. Later there was a star on the door.
swing with a cross-bar, used for feats of strength and agility, 1861, from French trapèze, from Late Latin trapezium (see trapezium), probably because the crossbar, the ropes and the ceiling formed a trapezium.
The French, to whose powers of invention (so long as you do not insist upon utility) there is no limit, have invented for the world the Trapeze .... [Chambers's Journal, July 6, 1861]
"an upper chamber," c. 1300, an extended sense from late Old English loft "the sky; the sphere of the air," from Old Norse lopt (Scandinavian -pt- pronounced like -ft-) "air, sky," originally "upper story, loft, attic," from Proto-Germanic *luftuz "air, sky" (source also of Old English lyft, Dutch lucht, Old High German luft, German Luft, Gothic luftus "air").
If this is correct, the sense development would be from "loft, ceiling" to "sky, air." Buck suggests a further connection with Old High German louft "bark," louba "roof, attic," etc., with development from "bark" to "roof made of bark" to "ceiling," though this did not directly inform the meaning "air, sky" (compare lodge (n.)). But Watkins says this is "probably a separate Germanic root." Meaning "gallery in a church" first attested c. 1500. From 1520s as "apartment over a stable" used for hay storage, etc.
1762, coined by Ben Franklin as the name for a glass harmonica, from Latin fem. of harmonicus (see harmonic); modern sense of "reeded mouth organ" is 1873, American English, earlier harmonicon (1825).
"powdered glass or crystal," by 1904, from French diamanté, past participle of diamanter "to set with diamonds," from Old French diamant (see diamond). Diamante also was a Middle English form of diamond.
1917, from Yiddish or directly from German spritzen "to squirt," from Middle High German sprützen "to squirt, sprout," from Proto-Germanic *sprut- (see sprout (v.)). Spritzer "glass of wine mixed with carbonated water" is from 1961.
