Menials working for Conservative female (10)
I believe the answer is:
underclass
'menials working for conservative female' is the definition.
I can't judge whether this defines the answer.
'working for conservative female' is the wordplay.
'working for' becomes 'under' (I've seen this in another clue).
'conservative' becomes 'C' (UK political abbreviation).
'female' becomes 'lass' (lass is a kind of female).
'under'+'c'+'lass'='UNDERCLASS'
Can you help me to learn more?
(Other definitions for underclass that I've seen before include "The institutionally disadvantaged" , "Lowest social stratum" .)
