Acknowledge an accomplishment, as in They really should give her credit for the work she's done. [
Late 1700s ]
The phrase is sometimes amplified to give credit where credit is due, meaning the acknowledgment should be to the person who deserves it. This expression was probably coined by Samuel Adams in a letter (October 29, 1777), which put it: “Give credit to whom credit due.” It is sometimes put give someone their due, as in We should really give Nancy her due for trying to sort out this mess.
