Relation flying from the east (8)
I believe the answer is:
oriental
'from the east' is the definition.
(I've seen this in another clue)
'relation flying' is the wordplay.
'flying' indicates anagramming the letters.
'relation' anagrammed gives 'ORIENTAL'.
(Other definitions for oriental that I've seen before include "Relation of Eastern origin" , "from the East End?" , "Eastern sort of relation" , "Eastern {8}" , "from Japan, say" .)
