| 词汇 | clean |
| 词根词缀 | 词源： O.E. clæne "clean, pure," from W.Gmc. *klainoz "clear, pure," from PIE base *gel- "to gleam" (cf. Gk. glene "eyeball," O.Ir. gel "bright"). As an adj., replaced in higher senses by clear, pure, but as a verb (c.1450) it has largely usurped what once belonged to cleanse. The adj. clean in the sense of "innocent" is from c.1300; that of "not lewd" is from 1867; that of "free of drug addiction" is 1950s. To take (someone) to the cleaners "get all of (someone's) money" is from 1932. 词根记忆： a. 清洁的,干净的v.除去..污垢,把…弄干净The lean man leans on the clean bean plant to read a leaf leaflet.瘦人斜靠在干净的豆科植物上读叶片传单. |
