Peerage appear nearly blue taking to Conservative (11)
I believe the answer is:
aristocracy
'peerage' is the definition.
(thesaurus)
'appear nearly blue taking to conservative' is the wordplay.
I cannot really see how this works, but
'blue' could be 'racy' ('racy' can be a synonym of 'blue') and 'racy' is present in the answer.
'to' is present in the answer.
'conservative' could be 'c' (abbreviation commonly used in UK politics) and 'c' is located in the answer.
The remaining letters 'aris' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for aristocracy that I've seen before include "Privileged class" , "those born ahead of others?" , "Upper class, nobility" , "Noble class" , "Upper classes" .)
