Graduates in Spanish that discover another language (6)
I believe the answer is:
basque
'graduates in spanish that discover another language' is the definition.
I know that 'spanish' relates to this answer.
'graduates in spanish that' is the wordplay.
'graduates' becomes 'bas' (I've seen this in other clues).
'in spanish that' becomes 'que' ('that' in Spanish).
'bas'+'que'='BASQUE'
(Other definitions for basque that I've seen before include "European language - close-fitting bodice" , "Member of people living in W Pyrenees" , "Member of Pyrenean people" , "Tight-fitting woman's bodice - coming from around Bilbao?" , "Person from western Pyrenees" .)
