Crackpot oriental aunt? (8)
I believe the answer is:
relation
'aunt?' is the definition.
(aunt is a kind of relation)
'crackpot oriental' is the wordplay.
'crackpot' indicates anagramming the letters (I've seen this in other clues).
'oriental' with letters rearranged gives 'RELATION'.
(Other definitions for relation that I've seen before include "Kinship; narrative" , "Person related by blood or marriage" , "Oriental kind of family connection" , "Link" , "Telling" .)
