Wrongly blame a Latino’s enthusiasm for dance (12)
I believe the answer is:
balletomania
'enthusiasm for dance' is the definition.
'wrongly blame a latino's' is the wordplay.
'wrongly' indicates anagramming the letters (I've seen this in other clues).
'blame'+'a'+'latino'='blamealatino'
'blamealatino' is an anagram of 'BALLETOMANIA'.
(Other definitions for balletomania that I've seen before include "love of dance" , "Fascination with elegant moves" .)
