Just; light (4)
I believe the answer is:
fair
I believe this is a double definition.
'just' is the first definition.
(just can mean fair in the sense of showing justice)
'light' is the second definition.
(I've seen this before)
(Other definitions for fair that I've seen before include "Sign following Pisces" , "legitimate" , "Attractive type of weather?" , "Blonde; beautiful" , "[OPPOSITE OF] Dark" .)
