Crossword Genius

More or less in the vicinity (5)

Ross

I believe the answer is:

about

I believe this is a double definition.

'more or less' is the first definition.
(synonyms)

'in the vicinity' is the second definition.
(synonyms)

(Other definitions for about that I've seen before include "On the subject of, approximately" , "in action" , "nearby" , "Regarding" , "in the offing?" .)
