Position to make out (4)
I believe the answer is:
spot
I believe this clue is a double definition.
'position' is the first definition.
('spot' can be a synonym of 'position')
'make out' is the second definition.
(I've seen this before)
'to' acts as a link.
(Other definitions for spot that I've seen before include "Detect" , "See - blemish" , "Dirty blemish" , "See - speckle" , "Observe - place" .)
