Charge pounds for fondle (4)
I believe the answer is:
feel
'fondle' is the definition.
(I've seen this before)
'charge pounds' is the wordplay.
'charge' becomes 'fee' (fee is a kind of charge**).
'pounds' becomes 'l' (L can represent the monetary pound).
'fee'+'l'='FEEL'
'for' is the link.
(Other definitions for feel that I've seen before include "Experience, perceive" , "Consider" , "Instinct" , "Sense or touch" , "Find by groping" .)
