| 词汇 | know what-s what |
| 词源 | know what’s what. Wrote Samuel Butler in Hudibras (1663): “He knew what’s what, and that’s as high/ As metaphysic wit can fly.” To know what is what is still to be a shrewd person, to know what is going on. The phrase is thought to derive from the old question in logic Quid est quid? “what is what,” one which someone would have to be very shrewd to answer. |
