A new local ground grant (9)
I believe the answer is:
allowance
'grant' is the definition.
(I know this)
'a new local ground' is the wordplay.
'ground' indicates an anagram ('grind' the letters into a new form).
'new'+'local'='newlocal'
'newlocal' with letters rearranged gives 'llowance'.
'a'+'llowance'='ALLOWANCE'
(Other definitions for allowance that I've seen before include "income" , "An amount granted for a period" , "Call on with awe for pocket-money or other grant" , "Money for agreed expenses" , "discount" .)
