Fee for one being looked after (6)
I believe the answer is:
charge
I believe this clue is a double definition.
'fee' is the first definition.
(I've seen this before)
'one being looked after' is the second definition.
(as in a young person looked after by a guardian)
'for' is the link.
(Other definitions for charge that I've seen before include "Rush to exact payment?" , "Care" , "Accuse of a crime" , "Fee; accuse" , "damage" .)
