Acknowledge donation (5)

I believe the answer is:

grant

I believe this is a double definition.

'acknowledge' is the first definition.
(thesaurus)

'donation' is the second definition.
(thesaurus)

(Other definitions for grant that I've seen before include "FILMSTAR" , "US president" , "Give (a right); gift" , "Give freely" , "19th century president" .)

I've seen this clue in The Telegraph.
