Inane is potentially the answer! (7)
I believe the answer is:
asinine
'inane is potentially the answer' is the definition.
I can't judge whether this definition defines the answer.
'inane is potentially' is the wordplay.
'potentially' indicates an anagram (letters have the potential to spell a new word).
'inane'+'is'='inaneis'
'inaneis' with letters rearranged gives 'ASININE'.
Can you help me to learn more?
(Other definitions for asinine that I've seen before include "Idiotic" , "Foolish like donkey" , "Extremely stupid or foolish" , "Foolish, silly" , "Is Annie? (Anag)" .)
