Having no match, with Lords wholly rejected? (8)
I believe the answer is:
peerless
'rejected?' is the definition.
Both the answer and definition are adjectives. Perhaps there's an association between them I don't understand?
'having no match with lords wholly' is the wordplay.
I cannot really see how this works, but
'match' could be 'peer' (synonyms) and 'peer' is located in the answer.
The remaining letters 'less' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for peerless that I've seen before include "Unparalleled, incomparable" , "Beyond compare" , "superb" , "Excellent" , "No Iolanthe performance could be so" .)
