Permit - strange to relate (8)
I believe the answer is:
tolerate
'permit' is the definition.
(I know that permit can be written as tolerate)
'strange to relate' is the wordplay.
'strange' indicates an anagram.
'to'+'relate'='torelate'
'torelate' is an anagram of 'TOLERATE'.
(Other definitions for tolerate that I've seen before include "Stomach" , "Be indulgent" , "Family relative" , "Abide" , "Treat fairly" .)
