Butler or maid (7)
I believe the answer is:
servant
I believe this is a double definition.
'butler' is the first definition.
(thesaurus)
'maid' is the second definition.
(thesaurus)
(Other definitions for servant that I've seen before include "Domestic - valet" , "Taverns (anag) -- retainer" , "Worker in household" , "Housekeeper" , "Butler, e.g." .)
