Don Quixote's squire (6,5)
I believe the answer is:
sancho panza
'don quixote's squire' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for sancho panza that I've seen before include "squire to a knight" , "Don Quixote's companion" , "Don Quixote's servant" , "Don Quixote's squire" , "Spanish squire" .)
