| 词汇 | bat |
| 词根词缀 | 词源： 1. bat (n.1) "a stick, a club," O.E. *batt "cudgel," perhaps from Celtic (cf. Ir. and Gael. bat, bata "staff, cudgel"), infl. by O.Fr. batte, from L.L. battre "beat;" all from PIE base *bhat- "to strike." As a kind of paddle used to play cricket, it is attested from 1706. 2. bat (n.2) "flying mammal" (order Chiroptera), 1570s, a dialect alteration of M.E. bakke, which is probably related to O.Swed. natbakka, O.Dan. nathbakkæ "night bat," and O.N. leðrblaka "leather flapper," so original sense is likely "flapper." The shift from -k- to -t- may have come through confusion of bakke with L. blatta "moth, nocturnal insect." O.E. word for the animal was hreremus, from hreran "to shake." As a contemptuous term for an old woman, perhaps a suggestion of witchcraft (cf. fly-by-night), or from bat as "prostitute who plies her trade by night" [Farmer, who calls it "old slang" and finds Fr. equivalent "night swallow" (hirondelle de nuit) "more poetic"]. 3. bat (v.) "to move the eyelids," 1847, Amer.Eng., from earlier sense of "flutter as a hawk" (1610s), a variant of bate (2) on the notion of fluttering wings. 词根记忆： n. 球拍,球棒,短棒;蝙蝠On the flat platform the bat will pat whatever hat it likes.在平坦的站台上,蝙蝠会拍打它喜欢的任何帽子. |
