Getting closer - in range possibly (7)
I believe the answer is:
nearing
'getting closer' is the definition.
(getting nearer)
'in range possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'in'+'range'='inrange'
'inrange' with letters rearranged gives 'NEARING'.
(Other definitions for nearing that I've seen before include "Moving towards" , "Approaching" , "Drawing closer to" , "Getting close to" .)
