His tediousness, one put up with (4)

I believe the answer is:
bore
'one put up with' is the definition.
(past tense of 'bear')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for bore that I've seen before include "Drill a hole in" , "Drill - pest" , "A tedious talkative person" , "Pierce or tire with tedium" , "Tiresome person - tidal flood" .)
