Stress caused by commuter journey? (5,4)
I believe the answer is:
drive home
'stress' is the definition.
(driving home is a kind of stressing)
'commuter journey?' is the wordplay.
I cannot quite see how this works, but
'journey?' could be 'drive' (drive is a kind of journey) and 'drive' is present in the answer.
The remaining letters 'home' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'caused by' acts as a link.
Can you help me to learn more?
(Other definitions for drive home that I've seen before include "Return journey" , "in the evening rush hour" , "Force (a nail) completely in" , "What some commuters do after work" , "Emphasise - return to one's abode?" .)
