Crime causing delay (4-2)
I believe the answer is:
hold-up
This might be a double definition.
'crime' is the first definition.
Both the definition and answer are singular nouns.
Maybe there's an association between them I don't understand?
'delay' is the second definition.
(I know that delay can be written as hold up)
'causing' acts as a link.
Can you help me to learn more?
(Other definitions for hold-up that I've seen before include "Commit armed robbery or keep aloft" , "Delay or show aloft" , "Suspend" , "Robbery with violence" , "Robbery at gunpoint" .)
