Get your bearings east of Asia (6)
I believe the answer is:
orient
I believe this clue is a triple definition!
'get your bearings' is the first definition.
(I've seen this in another clue)
'east' is the second definition.
(synonyms)
'of' is a link.
'asia' is the third definition.
(orient is a kind of asia)
(Other definitions for orient that I've seen before include "Determine (one's position) with reference to another point" , "Align; pearl" , "Get one's bearings - to the East?" , "Face towards the East?" , "Acquaint with position" .)
