Partially candlelit? Is mum displaying snobbery? (7)
I believe the answer is:
elitism
'snobbery?' is the definition.
(I've seen this in another clue)
'partially candlelit? is mum' is the wordplay.
'partially' indicates a hidden word.
'ELITISM' is hidden in the letters of 'candlelit is mum'.
'displaying' acts as a link.
(Other definitions for elitism that I've seen before include "Government by select group" , "Wanting the best" , "Exclusive attitude" , "Belief in government by a chosen few" , "going for the best" .)
