Governess (5)
I believe the answer is:
nanny
'governess' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nanny that I've seen before include "eg Mary Poppins" , "Nursemaid" , "Child's nurse or female goat" , "Producer of milk" , "Childminder - goat" .)
