Crossword creator (6)
I believe the answer is:
setter
'crossword creator' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for setter that I've seen before include "Bird trained to scent game" , "Breed of dog - crossword compiler" , "I may pose a problem" , "Red - - , dog" , "Thematic type [DOG]" .)
