Take care of, look after (4)
I believe the answer is:
tend
I believe this clue is a double definition.
'take care of' is the first definition.
(tending is a kind of taking care of)
'look after' is the second definition.
(tending is a kind of looking after)
(Other definitions for tend that I've seen before include "Incline - mind" , "Look after - there's a dent in it" , "Head" , "Wait on" , "Be predisposed or inclined" .)
