Car crash to avoid at a road junction (5)
I believe the answer is:
shunt
'car crash' is the definition.
(I've seen this before)
'avoid at a road junction' is the wordplay.
'avoid' becomes 'shun' (shunning is a kind of avoiding).
'at' is a charade indicator (letters next to each other).
'a road junction' becomes 't' (I am not sure about the 'road' bit.).
'shun'+'t'='SHUNT'
'to' is the link.
Can you help me to learn more?
(Other definitions for shunt that I've seen before include "Car crash (slang)" , "Move wagons around" , "Rear end collision" , "Sidetrack" , "Divert into alternative course, like train" .)
