Most ridiculous amateur in bar performing set (7)
I believe the answer is:
inanest
'most ridiculous' is the definition.
Both the answer and definition are superlative adjectives. Perhaps you can see a link between them that I don't see?
'amateur in bar performing set' is the wordplay.
'amateur' becomes 'a'.
'in' is an insertion indicator.
'bar' becomes 'inn' (I've seen this in other clues).
'performing' indicates anagramming the letters.
'set' with letters rearranged gives 'est'.
'inn'+'est'='innest'
'a' inserted within 'innest' is 'INANEST'.
Can you help me to learn more?
(Other definitions for inanest that I've seen before include "Exhibiting minimal sense" , "Most stupid" , "most senseless" , "Most silly" , "Most cuckoo" .)
