- put-on (n.)
[put-on 词源字典]
- "ruse, deception," 1937, from earlier adjectival meaning "assumed, feigned" (1620s), a figurative extension of the notion of putting on costumes or disguises; from put (v.) + on (adv.). The expression put (someone) on "play a trick on" seems to be a back-formation from the noun.[put-on etymology, put-on origin, 英语词源]
