Mean about donation (9)
I believe the answer is:
represent
'mean' is the definition.
(I know that mean can be written as represent)
'about donation' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'donation' becomes 'present' (I've seen this before).
're'+'present'='REPRESENT'
(Other definitions for represent that I've seen before include "show" , "Serve as a symbol for" , "Portray" , "Illustrate" , "Ambassadors do it" .)
