Individual pressing his mum regularly for fruit (9)
I believe the answer is:
persimmon
'for fruit' is the definition.
(persimmon is a kind of fruit)
'individual pressing his mum regularly' is the wordplay.
'individual' becomes 'person' (synonyms).
'pressing' means one lot of letters goes inside another.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'his'+'mum'='hismum'
The alternating letters of 'hismum' are 'imm'.
'person' placed around 'imm' is 'PERSIMMON'.
(Other definitions for persimmon that I've seen before include "Orange fruit resembling a plum - miner's mop (anag)" , "Tropical fruit" , "Edible fruit" .)
