Venture to break in with force (10)
I believe the answer is:
enterprise
'venture' is the definition.
(I've seen this before)
'break in with force' is the wordplay.
'break in' becomes 'enter' (I've seen this before).
'with' says to put letters next to each other.
'force' becomes 'prise' (as in prising or forcing something open).
'enter'+'prise'='ENTERPRISE'
'to' acts as a link.
(Other definitions for enterprise that I've seen before include "Bold resourcefulness" , "drug business" , "business concern" , "Initiative - undertaking - business" , "Company" .)
