Whole of community (4)
I believe the answer is:
unit
'whole' is the definition.
(unit is a kind of whole)
'of community' is the wordplay.
'of' indicates the answer is hidden within the clue.
'UNIT' is hidden in the letters of 'community'.
(Other definitions for unit that I've seen before include "Entity making up part of a whole" , "Group that's part of a larger organisation" , "A single, complete item" , "Single undivided whole" , "Kitchen element?" .)
