Unexceptional without trendy path (5)
I believe the answer is:
route
'path' is the definition.
(I know that path can be written as route)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for route that I've seen before include "Way, line" , "Way travelled" , "Way to travel" , "Established line of trave" , "Course followed" .)
