Endure - strange to relate (8)
I believe the answer is:
tolerate
'endure' is the definition.
(I know that endure can be written as tolerate)
'strange to relate' is the wordplay.
'strange' is an anagram indicator.
'to'+'relate'='torelate'
'torelate' with letters rearranged gives 'TOLERATE'.
(Other definitions for tolerate that I've seen before include "Withstand" , "Suffer" , "Turn a blind eye to" , "Family relative" , "Put up with something or somebody" .)
