Fair and easy (5)
I believe the answer is:
light
I believe this clue is a double definition.
'fair' is the first definition.
(I've seen this before)
'easy' is the second definition.
('light' can be similar in meaning to 'easy')
'and' acts as a link.
(Other definitions for light that I've seen before include "free gift from The Sun" , "Opposite of dark" , "Beam" , "Eminent person" , "Moored vessel warning sailors of a hazard" .)
