Suffer, strange to relate (8)
I believe the answer is:
tolerate
'suffer' is the definition.
('tolerate' can be a synonym of 'suffer')
'strange to relate' is the wordplay.
'strange' is an anagram indicator.
'to'+'relate'='torelate'
'torelate' is an anagram of 'TOLERATE'.
(Other definitions for tolerate that I've seen before include "Put up with, permit without protest" , "Accept or bear with" , "Abide" , "Allow" , "Stomach" .)
