Accustom or align (6)
I believe the answer is:
orient
I believe this is a double definition.
'accustom' is the first definition.
(I've seen this in another clue)
'align' is the second definition.
(I've seen this in another clue)
(Other definitions for orient that I've seen before include "Face towards the East?" , "Align (in a particular direction)" , "Leyton -- FC" , "Asia" , "Get one's bearings - to the East?" .)
