Junction that causes disgust (7)
I believe the answer is:
turnoff
'junction that causes disgust' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
This is all the clue.
Can you help me to learn more?
(Other definitions for turnoff that I've seen before include "Cause of boredom/disgust" , "Something generating distaste" , "Something eliciting distaste" , "Branching road" , "Leave main road; close (tap)" .)
