| 词汇 | deafen |
| 词根词缀 | 词源： 1590s, "to make deaf," from deaf. The earlier verb was simply deaf (mid-15c.). For "to become deaf, to grow deaf," O.E. had adeafian (intrans.), which survived into M.E. as deave but then took on a transitive sense from mid-14c. and sank from use except in dialects (where it mostly has transitive and figurative senses), leaving English without an intransitive verb here. |
