Closer (6)
I believe the answer is:
nearer
'closer' is the definition.
('near' can be a synonym of 'close')
This is all the clue.
(Other definitions for nearer that I've seen before include "Closer, not so far" , "Closer - my God to Thee?" , "Closer at hand" , "Well-known hymn '. . . . . . my God to Thee'" , "Not so far away" .)
