Intuitive guess or feeling (5)
I believe the answer is:
hunch
I believe this clue is a double definition.
'intuitive guess' is the first definition.
(I've seen this before)
'feeling' is the second definition.
(I know that hunch is a type of feeling)
(Other definitions for hunch that I've seen before include "Bend over" , "Premonition; hump" , "protuberance" , "Intuitive guess" , "Idea based on intuition" .)
