Honouring none dressed with flashy jewellery (9)
I believe the answer is:
ennobling
'honouring' is the definition.
(ennobling is a kind of honouring)
'none dressed with flashy jewellery' is the wordplay.
'dressed' indicates an anagram ('dress' can mean 'prepare').
'with' means one lot of letters go next to another.
'flashy jewellery' becomes 'bling' (I've seen this before).
'none' anagrammed gives 'enno'.
'enno'+'bling'='ENNOBLING'
(Other definitions for ennobling that I've seen before include "Making one count, perhaps" , "Entitling" , "Honouring" .)
