Great anger on the way (4,4)
I believe the answer is:
road rage
'great anger on the way' is the definition.
I can't judge whether this definition defines the answer.
'anger on the way' is the wordplay.
'anger' becomes 'rage' (rage is a kind of anger).
'on' is a charade indicator (letters next to each other).
'the way' becomes 'road' (road is a kind of way).
'rage' after 'road' is 'ROAD RAGE'.
Can you help me to learn more?
(Other definitions for road rage that I've seen before include "Driver's violent anger" , "Motorway madness?" , "making of a scene for travellers?" , "Violently aggressive behaviour by driver" , "aggression when driving" .)
