Servant, male help (4)
I believe the answer is:
maid
'servant' is the definition.
(maid is a kind of servant)
'male help' is the wordplay.
'male' becomes 'm' (common abbreviation).
'help' becomes 'aid' ('aid' can be a synonym of 'help').
'm'+'aid'='MAID'
(Other definitions for maid that I've seen before include "One in service" , "Damsel" , "Young woman - servant" , "employee" , "Female domestic servant" .)
