Occupied with being generous? (4)
I believe the answer is:
full
This clue is a double definition.
'occupied' is the first definition.
(thesaurus)
'being generous?' is the second definition.
(thesaurus)
'with' acts as a link.
(Other definitions for full that I've seen before include "Containing as much as possible" , "At maximum capacity" , "(Of a figure) plump or rounded" , "At capacity; rounded" , "Treat cloth; complete" .)
