Firm, therefore, accepts emergency regulations, initially in agreement (9)
I believe the answer is:
coherence
'agreement' is the definition.
(thesaurus)
'firm therefore accepts emergency regulations initially' is the wordplay.
'firm' becomes 'co' (a firm is a company).
'therefore' becomes 'hence' ('hence' can be a synonym of 'therefore'**).
'accepts' is an insertion indicator.
'initially' indicates taking the first letters.
The first letters of 'emergency regulations' is 'er'.
'hence' placed around 'er' is 'herence'.
'co'+'herence'='COHERENCE'
'in' acts as a link.
(Other definitions for coherence that I've seen before include "ability to talk sense" , "sense of unity" , "Sticking together" , "Logical consistency" , "union" .)
