Scaramouche in imitation silver dress back before ten (11)
I believe the answer is:
braggadocio
'back before ten' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'scaramouche in imitation silver dress' is the wordplay.
I cannot quite understand how this works, but
'silver' could be 'ag' (Ag is the chemical symbol for silver) and 'ag' is present in the answer.
'dress' could be 'do' (synonyms) and 'do' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for braggadocio that I've seen is " Boastful and arrogant behaviour".)
