Servants of Ximenes? (3)
I believe the answer is:
men
'servants' is the definition.
(man can mean a personal servant)
'of ximenes?' is the wordplay.
'of' says the answer is hidden in the clue.
'MEN' is hidden within 'ximenes'.
(Other definitions for men that I've seen before include "Chess pieces" , "Adult males" , "- - -o'-war (ships)" , "Human males" , "'So many ..., so many opinions'" .)
