Far away, on a little bit (6)
I believe the answer is:
remote
'far away' is the definition.
(I've seen this in another clue)
'on a little bit' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'a little bit' becomes 'mote' (I've seen this in another clue).
're'+'mote'='REMOTE'
(Other definitions for remote that I've seen before include "Cold" , "Device for controlling apparatus from a distance" , "Withdrawn" , "Far way like meteor" , "Slight possibility" .)
