Degree question university set in extremely simple language (6)
I believe the answer is:
basque
'language' is the definition.
(thesaurus)
'degree question university set in extremely simple' is the wordplay.
'degree' becomes 'ba' (Bachelor of Arts**).
'question' becomes 'q'.
'university' becomes 'u'.
'set in' indicates putting letters inside.
'extremely' says to hollow out the word (remove centre letters).
'simple' with its centre removed is 'se'.
'q'+'u'='qu'
'qu' inserted within 'se' is 'sque'.
'ba'+'sque'='BASQUE'
(Other definitions for basque that I've seen before include "One lives in the Western Pyrenees on the Atlantic coast" , "Type of close-fitting bodice" , "People living in the Western Pyrenees in France and Spain" , "Language of SW France" , "W. Pyrenean language; bodice" .)
