Most ineffectual bees felt funny (8)
I believe the answer is:
feeblest
'most ineffectual' is the definition.
Both the definition and answer are superlative adjectives. Maybe you can see an association between them that I don't see?
'bees felt funny' is the wordplay.
'funny' is an anagram indicator.
'bees'+'felt'='beesfelt'
'beesfelt' anagrammed gives 'FEEBLEST'.
Can you help me to learn more?
(Other definitions for feeblest that I've seen before include "Most ineffective" , "most faint" , "Most pathetic" , "Most inadequate" .)
