Revolutionary and monster becoming accessories (10)
I believe the answer is:
adornments
'accessories' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps you can see an association between them that I don't see?
'revolutionary and monster' is the wordplay.
'revolutionary' indicates an anagram.
'and'+'monster'='andmonster'
'andmonster' with letters rearranged gives 'ADORNMENTS'.
'becoming' acts as a link.
Can you help me to learn more?
(Another definition for adornments that I've seen is " Embellishments".)
