School gets stick about a main thoroughfare (8)
I believe the answer is:
highroad
'a main thoroughfare' is the definition.
'highroad' can be an answer for 'thoroughfare' (thesaurus). I'm not sure about the 'a main' bit.
'school gets stick' is the wordplay.
'school' becomes 'high' (high school is a kind of school).
'gets stick' becomes 'road' (I can't explain this - if you can you should believe this answer much more).
'high'+'road'='HIGHROAD'
'about' acts as a link.
Can you help me to learn more?
(Another definition for highroad that I've seen is " Upper route?".)
