Correct behaviour shown by English company during strike (7)
I believe the answer is:
decorum
'correct behaviour' is the definition.
(I've seen this before)
'english company during strike' is the wordplay.
'english' becomes 'e' (abbreviation).
'company' becomes 'co' (abbreviation).
'during' is an insertion indicator.
'strike' becomes 'drum' (I can't justify this - if you can you should give a lot more credence to this answer).
'e'+'co'='eco'
'eco' inserted into 'drum' is 'DECORUM'.
'shown by' is the link.
Can you help me to learn more?
(Other definitions for decorum that I've seen before include "Dignity of behaviour or proceedings" , "Correct behaviour" , "Protocol" , "good behaviour" , "Proper form" .)
