Spanish saint (6)
I believe the answer is:
teresa
'spanish saint' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for teresa that I've seen before include "Saint" , "Mother . . . . . ., saintly nun of Calcutta" , "Mother ..., who ministered to the poor in India" , "Mother...saintly nun of Calcutta" , "Does 'e stare at the girl?" .)
