Spanish "mister" (5)
I believe the answer is:
senor
'spanish mister' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for senor that I've seen before include "way of addressing Figaro, say" , "'Mister' in Spain" , "A Spanish mister" , "Gentlemanly address in Spain" , "Snore (anag.)" .)
