Supervise for a small charge (4-3)
I believe the answer is:
baby-sit
'charge' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'supervise for a small' is the wordplay.
'supervise' becomes 'sit' (I can't justify this - if you can you should believe this answer much more).
'for' says to put letters next to each other (I've seen this in other clues).
'a small' becomes 'baby'.
'sit' after 'baby' is 'BABY-SIT'.
Can you help me to learn more?
(Other definitions for baby-sit that I've seen before include "Look after children temporarily" , "Mind small children while parents have a night out" , "Look after young children" , "Look after youngsters" , "Relieve parents" .)
