Fatigue with traffic fumes (7)
I believe the answer is:
exhaust
This clue might be a double definition.
'fatigue' is the first definition.
(I know that exhaust is a more specific form of the action fatigue)
'traffic fumes' is the second definition.
'exhaust' can be an answer for 'fumes' (synonyms). I'm unsure of the 'traffic' bit.
'with' is the link.
Can you help me to learn more?
(Other definitions for exhaust that I've seen before include "Tire utterly or fumes-dispersing device in car" , "Empty" , "Gases ejected from an engine" , "Deplete" , "Drain completely" .)
