词汇 | buoy |
词根词缀 | 词源: buoy (n.) 1296, perhaps from either O.Fr. buie or M.Du. boeye, both from W.Gmc. *baukn "beacon" (cf. O.H.G. bouhhan, O.Fris. baken). OED, however, supports M.Du. boeie, or O.Fr. boie "fetter, chain" (see boy), "because of its being fettered to a spot." The verb, in the fig. sense (of spirits, etc.) is from 1645. |
