Donate a sum of money, for building repairs, say? (5)
I believe the answer is:
grant
'donate' is the definition.
(thesaurus)
'a sum of money for building repairs say?' is the wordplay.
I cannot really see how this works, but
'a' could be 'an' and 'an' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for grant that I've seen before include "cash allowance?" , "Cary, Duncan or Ulysses S?" , "Bestow; bursary" , "Agree to - bursary" , "Permit" .)
