Handle fine fish (4)
I believe the answer is:
feel
'handle' is the definition.
(I've seen this in another clue)
'fine fish' is the wordplay.
'fine' becomes 'f' (abbreviation).
'fish' becomes 'eel' (eel is a type of fish).
'f'+'eel'='FEEL'
(Other definitions for feel that I've seen before include "Fondle" , "Instinct" , "Have sensation of" , "Be aware of - texture" , "impression" .)
