Language used by Sheba’s queen? (6)
I believe the answer is:
basque
'language' is the definition.
(I've seen this before)
'used by sheba's queen?' is the wordplay.
'used by' indicates a hidden word.
'BASQUE' is hidden within 'shebas queen'.
(Other definitions for basque that I've seen before include "People living in the Western Pyrenees in France and Spain" , "Native of western Pyrenees, traditionally rebellious" , "Bodice - West Pyrenean" , "Native of French-Spanish border area" , "Person from western Pyrenees" .)
