Close at hand, imminent (4)
I believe the answer is:
nigh
This clue is a double definition.
'close at hand' is the first definition.
(I've seen this before)
'imminent' is the second definition.
(I've seen this in another clue)
(Other definitions for nigh that I've seen before include "Near at hand" , "Just round the corner" , "comes close" , "Almost (arch.)" , "Near (poetic)" .)
