African expedition exposed overseas, perhaps (4)
I believe the answer is:
afar
'perhaps' is the definition.
Both the definition and answer are adverbs. Perhaps you can see an association between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for afar that I've seen before include "Many miles away" , "quite some distance" , "Inhabitant of Ethiopia" , "long way back" , "At a distance (poetic)" .)
