Horse trading clique? (3)
I believe the answer is:
set
'clique?' is the definition.
(a clique is a social set)
'horse trading' is the wordplay.
'SET' is hidden within the letters.
However, I'm unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for set that I've seen before include "several games" , "Scenery etc. for a drama" , "Arrange; a party" , "Complete collection" , "decline" .)
