Lowly servant (6)
I believe the answer is:
menial
I believe this is a double definition.
'lowly' is the first definition.
(synonyms)
'servant' is the second definition.
(I know that menial is a type of servant)
(Other definitions for menial that I've seen before include "(Of work) unskilled" , "Inferior like servant" , "'Humble, lowly, work say (6)'" , "A drudge" , "Unskilled, degrading" .)
