Stop person having a break, reportedly (6)
I believe the answer is:
arrest
'stop' is the definition.
(synonyms)
'person having a break reportedly' is the wordplay.
I cannot really understand how this works, but
'a' is present in the answer.
'break' could be 'rest' (a rest is taking a break) and 'rest' is located in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for arrest that I've seen before include "Nab" , "Seize (a crime suspect)" , "Bring to a standstill" , "Collar" , "apprehend a law-breaker" .)
