Have a hunch, from experience (4)
I believe the answer is:
feel
I believe this clue is a double definition.
'have a hunch' is the first definition.
(I've seen this in another clue)
'experience' is the second definition.
(I know that experience can be written as feel)
'from' acts as a link.
(Other definitions for feel that I've seen before include "Have a belief; touch" , "Experience, perceive" , "Perceive, sense" , "Have sensation of" , "Be aware of - texture" .)
