Show particular interest in running order for assembly (10,4)
I believe the answer is:
production line
'assembly' is the definition.
(thesaurus)
'show particular interest in running order' is the wordplay.
I cannot quite understand how this works, but
'in' is within the answer.
'running' could be 'on' (eg when a machine is running it is on) and 'on' is found in the answer.
'order' could be 'o' (abbreviation e.g. in British honours OM, OBE etc.) and 'o' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for production line that I've seen before include "part of factory" , "Manufacturing set-up" , "Factory process" , "process of constructing many" .)
