Experienced bore (3)
I believe the answer is:
had
I believe this is a double definition.
'experienced' is the first definition.
(have can mean to experience or go through)
'bore' is the second definition.
('have' can be a synonym of 'bear')
(Other definitions for had that I've seen before include "Was in possession of" , "Possessed; cheated" , "Was bound to be - caught" , "Did trick" , "kept" .)
