Misplacing small vest, I riled runner-up (6,9)
I believe the answer is:
silver medallist
'runner-up' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see a link between them that I don't see?
'misplacing small vest i riled' is the wordplay.
'misplacing' indicates anagramming the letters (I've seen 'misplaced' mean this).
'small'+'vest'+'i'+'riled'='smallvestiriled'
'smallvestiriled' with letters rearranged gives 'SILVER MEDALLIST'.
Can you help me to learn more?
(Other definitions for silver medallist that I've seen before include "Athlete" , "Prizewinner" .)
