英文词源

crop: crop: [OE] Old English cropp meant ‘bird’s craw’ and ‘rounded head of a plant’, and it was presumably the latter that gave rise to the word’s most familiar modern sense, ‘cultivated plant produce’, at some time in the 13th century. Its relatives in other Germanic languages, including German kropf and Dutch krop, are used for ‘bird’s craw’ but also for various bodily swellings in the throat and elsewhere, indicating the word’s underlying meaning is ‘round mass, lump’.

Its Germanic ancestor, *kruppō, was borrowed into Vulgar Latin as *cruppa, which made its way via Old French into English as croup ‘horse’s (round) rump’ [13], and as the derivative crupper [13]. Croupier [18] is based on French croupe, having originally meant ‘person who rides on the rump, behind the saddle’. The Germanic base *krup- ‘round mass, lump’ is also the ancestor of English group.
=> croup, croupier, crupper, group
crop (n.): Old English cropp "bird's craw," also "head or top of a sprout or herb." The common notion is "protuberance." Cognate with Old High German kropf, Old Norse kroppr. Meaning "harvest product" is c. 1300, probably through the verbal meaning "cut off the top of a plant" (c. 1200).
crop (v.): "cut off the top of a plant," c. 1200, from crop (n.). The general meaning of "to cut off" is mid-15c. Related: Cropped; cropping. Women's fashion crop top is attested from 1984.
