A super one makes continentals (9)
I believe the answer is:
europeans
'continentals' is the definition.
(I've seen this before)
'a super one makes' is the wordplay.
'makes' indicates an anagram.
'a'+'super'+'one'='asuperone'
'asuperone' is an anagram of 'EUROPEANS'.
(Other definitions for europeans that I've seen before include "Continentals" , "Frenchmen, Irishwomen, for instance" , "Irish and French people, say" , "The French and Italians, say" .)
