Basically gutless? Bizarrely the opposite! (6)
I believe the answer is:
'opposite' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'basically gutless? bizarrely' is the wordplay.
'gutless?' says to hollow out the word (remove centre letters) (I've seen 'gutless' mean this).
'bizarrely' is an anagram indicator.
'basically' with its middle removed is 'baslly'.
'baslly' with letters rearranged gives 'BALLSY'.
'the' acts as a link.
Can you help me to learn more?
