- acquit[acquit 词源字典]
- acquit:  Acquit is ultimately related to quiet. The Latin noun quies, from which we get quiet, was the basis of a probable verb *quietare, later *quitare, whose original meaning, ‘put to rest’, developed to ‘settle’, as in ‘settle a debt’. With the addition of the prefix ad- this passed into Old French as a(c)quiter, and thence into English (still with the ‘settling or discharging debts’ meaning). The currently most common sense, ‘declare not guilty’, did not appear until the 14th century, and the most recent meaning, ‘conduct oneself in a particular way’, developed from the notion of discharging one’s duties.
