Over-the-top misrepresentation of exes' vices (9)
I believe the answer is:
excessive
'over' is the definition.
(thesaurus)
'of exes' vices' is the wordplay.
'of' indicates an anagram (the answer comes from or 'of' the letters).
'exes'+'vices'='exesvices'
'exesvices' with letters rearranged gives 'EXCESSIVE'.
'the-top misrepresentation' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for excessive that I've seen before include "Beyond normal limits" , "Disproportionate" , "Over the top" , "More than is desirable" , "Immoderate" .)
