Bring up sister? (5)
I believe the answer is:
nurse
This clue is a double definition.
'bring up' is the first definition.
(thesaurus)
'sister?' is the second definition.
(thesaurus)
(Other definitions for nurse that I've seen before include "Runes (anag)" , "Cherish" , "Medical worker" , "Hospital tender" , "Qualified carer" .)
