Run into when you go out (6)
I believe the answer is:
strike
This could be a double definition.
'run into' is the first definition.
(synonyms)
'go out' is the second definition.
(thesaurus)
'when you' acts as a link.
This may not be right. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for strike that I've seen before include "Failure to hit ball" , "make an impact" , "Work stoppage over industrial dispute" , "Hit forcibly" , "Hit; withhold labour" .)
