Word before check or course (3)
I believe the answer is:
gut
'word before check or course' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gut that I've seen before include "Eviscerate" , "Belly; instinctive (feeling)" , "good for Goering" , "Food processor" , "Part of intestine" .)
