Give to charity (6)
I believe the answer is:
donate
'give to charity' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for donate that I've seen before include "Atoned (anag)" , "Muhammad -, US boxer" , "Give to a charity or good cause" , "Give as a gift as to charity" , "Give - present" .)
