With apprehension, stop (6)
I believe the answer is:
arrest
This clue could be a double definition.
'with apprehension' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'stop' is the second definition.
(I know that stop can be written as arrest)
Can you help me to learn more?
(Other definitions for arrest that I've seen before include "apprehend a law-breaker" , "Take into legal custody" , "Cause to stop" , "Stop or slow down the progress of" , "Collar" .)
