early 15c., "hairy, shaggy, bristling," from Latin horridus "bristly, prickly, rough, horrid, frightful, rude, savage, unpolished," from horrere "to bristle with fear, shudder" (see horror). Meaning "horrible, causing horror" is from c. 1600. Sense weakened 17c. to "unpleasant, offensive."
[W]hile both [horrible and horrid] are much used in the trivial sense of disagreeable, horrible is still quite common in the graver sense inspiring horror, which horrid tends to lose .... [Fowler]
early 14c., croket, "ornamental roll or lock of hair," from Anglo-French crocket, from northern French form of Old French crochet, croquet, literally "a hook" (see crochet (n.)). In medieval architecture, "pointed ornamental device on a sloping pinnacle, gable, etc.," late 14c. Related: Crocketed.
raptorial bird, 1708, from Latin accipiter, a generic name for birds of prey, especially the common hawk. According to de Vaan, "generally assumed" to be from a Proto-Italic *aku-petri- "having pointed (that is, 'swift') wings" (see acro- + ptero-) and compares Greek okypteros "with swift wings," Sanskrit asu-patvan- "flying swiftly," "all of which are used as epithets to birds of prey." Under this theory the initial acc- is by influence of the verb accipere "to take" (whence also Latin acceptor "falcon;" see accept). Or the sense could be literal, "with pointed wings." The proper plural would be accipitres. Related: Accipitral; accipitrine (1809).
In England, the usual name is rocket (see rocket (n.1)), which is from Italian ruchetta via French roquette. It also sometimes is called hedge mustard.
