Rest set out ways (7)
I believe the answer is:
streets
'ways' is the definition.
(street is a kind of way)
'rest set out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'rest'+'set'='restset'
'restset' anagrammed gives 'STREETS'.
(Other definitions for streets that I've seen before include "Avenues" , "significantly ahead?" , "Town thoroughfares" , "Ways" , "Built-up roads" .)
