Equitable trade show (4)
I believe the answer is:
fair
This clue is a double definition.
'equitable' is the first definition.
(synonyms)
'trade show' is the second definition.
(I've seen this before)
(Other definitions for fair that I've seen before include "clean" , "Impartial, so-so" , "[OPPOSITE OF] Dark" , "honest" , "Just - blonde - outdoor entertainment" .)
