Within arm's reach (4)
I believe the answer is:
near
'within arm's reach' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for near that I've seen before include "Parsimonious (informal)" , "Not far distant in time or space etc." , "Close at hand" , "Close; parsimonious" , "Close; almost" .)
