Musical that might be very good or very bad (6)
I believe the answer is:
wicked
I believe this clue is a quadruple definition!!
'musical' is the first definition.
'that might be' is a link.
'very' is the second definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I don't see?
'good' is the third definition.
(thesaurus)
'or' acts as a link.
'very bad' is the fourth definition.
(Other definitions for wicked that I've seen before include "Morally bad or wrong" , "Ungodly; excellent (sl.)" , "Very bad, or very good nowadays" , "Evil or morally wrong" , "[SMASHING, COOL, DANDY]" .)
