Just set in order (5)
I believe the answer is:
right
I believe this is a triple definition!
'just' is the first definition.
(similar in meaning)
'set' is the second definition.
(right is a kind of set)
'in order' is the third definition.
(I've seen this in another clue)
(Other definitions for right that I've seen before include "Authority - one hand" , "It's what you deserve" , "Correct; entitlement" , "blue, politically" , "Correct; proper" .)
