Just enter number into remote (4)
I believe the answer is:
fair
'just' is the definition.
(just can mean fair in the sense of showing justice)
'number into remote' is the wordplay.
'number' becomes 'i' (I is an example).
'into' indicates putting letters inside.
'remote' becomes 'far' (similar in meaning).
'i' placed inside 'far' is 'FAIR'.
'enter' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for fair that I've seen before include "See 14" , "nothing special" , "Trade exhibition, (of weather) fine" , "Just; passable" , "Just treatment of others" .)
