Part of Somerset advertisement for return of fruit (5)
I believe the answer is:
dates
'fruit' is the definition.
(I've seen this before)
'part of somerset advertisement for return' is the wordplay.
'part of' says the answer is hidden in the clue.
'return' shows that the letters should be reversed in order.
'setad' can be found hidden inside 'somerset advertisement for'.
'setad' back-to-front is 'DATES'.
'of' is the link.
(Other definitions for dates that I've seen before include "Dried fruit" , "Sated (anag) - fruit" , "Goes steady" , "Occasions" , "Fruits and pre-arranged meetings" .)
