Regulated state that's sought by salesman? (5)
I believe the answer is:
order
This could be a double definition.
'regulated state' is the first definition.
'order' can be an answer for 'state' (order is a kind of state). I'm not certain of the 'regulated' bit.
'sought by salesman?' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'that's' is the link.
Can you help me to learn more?
(Other definitions for order that I've seen before include "Jesuits, say" , "kind > direction" , "Tidy and settled condition" , "Reserved goods" , "Tidy state - that's a command" .)
