Company and former partner having one way to live together (7)
I believe the answer is:
coexist
'live together' is the definition.
(I've seen this before)
'company and former partner having one way' is the wordplay.
'company' becomes 'co' (abbreviation).
'and' is a charade indicator (letters next to each other).
'former partner' becomes 'ex' (an ex-partner).
'having one' becomes 'i' (I am not sure about this - if you are sure you should believe this answer much more).
'way' becomes 'st' (abbreviation for street).
'co'+'ex'+'i'+'st'='COEXIST'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for coexist that I've seen before include "Live together peacefully" , "Live together in harmony" , "Avoid conflict" , "Live together in peace" , "Live side by side" .)
