Be inclined to do some nursing (4)
I believe the answer is:
tend
'be inclined' is the definition.
(synonyms)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for tend that I've seen before include "lean in a certain direction" , "Go in a particular direction; look after" , "Wait on" , "Be predisposed or inclined" , "Look after (a patient)" .)
