Business to come in with force (10)
I believe the answer is:
enterprise
'business' is the definition.
(enterprise can mean a business)
'come in with force' is the wordplay.
'come in' becomes 'enter' (synonyms).
'with' is a charade indicator (letters next to each other).
'force' becomes 'prise' (as in forcing or prising something open).
'enter'+'prise'='ENTERPRISE'
'to' acts as a link.
(Other definitions for enterprise that I've seen before include "business concern" , "Company" , "Get-up-and-go - venture" , "Initiative - undertaking - business" , "New project" .)
