bitchy (adj.)youdaoicibaDictYouDict[bitchy 词源字典]
1925, U.S. slang, "sexually provocative;" later (1930s) "spiteful, catty, bad-tempered" (usually of females); from bitch + -y (2). Earlier in reference to male dogs though to look less rough or coarse than usual.
Mr. Ramsay says we would now call the old dogs "bitchy" in face. That is because the Englishmen have gone in for the wrong sort of forefaces in their dogs, beginning with the days when Meersbrook Bristles and his type swept the judges off their feet and whiskers and an exaggerated face were called for in other varieties of terriers besides the wire haired fox. [James Watson, "The Dog Book," New York, 1906]

locust (n.1)youdaoicibaDictYouDict
"grasshopper," early 14c., borrowed earlier in Old French form languste (c. 1200), from Latin locusta "locust, lobster" (see lobster).
In the Hebrew Bible there are nine different names for the insect or for particular species or varieties; in the English Bible they are rendered sometimes 'locust,' sometimes 'beetle,' 'grasshopper,' 'caterpillar,' 'palmerworm,' etc. The precise application of several names is unknown. [OED]

take (v.)youdaoicibaDictYouDict
late Old English tacan "to take, seize," from a Scandinavian source (such as Old Norse taka "take, grasp, lay hold," past tense tok, past participle tekinn; Swedish ta, past participle tagit), from Proto-Germanic *takan- (cognates: Middle Low German tacken, Middle Dutch taken, Gothic tekan "to touch"), from Germanic root *tak- "to take," of uncertain origin, perhaps originally meaning "to touch." As the principal verb for "to take," it gradually replaced Middle English nimen, from Old English niman, from the usual West Germanic *nem- root (source of German nehmen, Dutch nemen; see nimble).

OED calls take "one of the elemental words of the language;" take up alone has 55 varieties of meaning in that dictionary's 2nd print edition. Basic sense is "to lay hold of," which evolved to "accept, receive" (as in take my advice) c. 1200; "absorb" (take a punch) c. 1200; "choose, select" (take the high road) late 13c.; "to make, obtain" (take a shower) late 14c.; "to become affected by" (take sick) c. 1300.

Take five is 1929, from the approximate time it takes to smoke a cigarette. Take it easy first recorded 1880; take the plunge "act decisively" is from 1876; take the rap "accept (undeserved) punishment" is from 1930. Phrase take it or leave it is recorded from 1897. To take it out on (someone or something) "vent one's anger on other than what caused it" is by 1840.
taste (v.)youdaoicibaDictYouDict
c. 1300, "to touch, to handle," from Old French taster "to taste, sample by mouth; enjoy" (13c.), earlier "to feel, touch, pat, stroke" (12c., Modern French tâter), from Vulgar Latin *tastare, apparently an alteration (perhaps by influence of gustare) of taxtare, a frequentative form of Latin taxare "evaluate, handle" (see tax (v.)). Meaning "to take a little food or drink" is from c. 1300; that of "to perceive by sense of taste" is recorded from mid-14c. Of substances, "to have a certain taste or flavor," it is attested from 1550s (replaced native smack (v.3) in this sense). For another PIE root in this sense, see gusto.
The Hindus recognized six principal varieties of taste with sixty-three possible mixtures ... the Greeks eight .... These included the four that are now regarded as fundamental, namely 'sweet,' 'bitter,' 'acid,' 'salt.' ... The others were 'pungent' (Gk. drimys, Skt. katuka-), 'astringent' (Gk. stryphnos, Skt. kasaya-), and, for the Greeks, 'rough, harsh' (austeros), 'oily, greasy' (liparos), with the occasional addition of 'winy' (oinodes).
