Be inclined to nurse
I believe the answer is:
tend
This clue is a double definition.
'be inclined' is the first definition.
(synonyms)
'nurse' is the second definition.
(I've seen this before)
'to' acts as a link.
(Other definitions for tend that I've seen before include "Care for, nurse" , "Have leaning towards - put dent in (4)" , "Head" , "Look after (someone)" , "Look after, take care of" .)
