Live to own things and show one’s breeding (6)

I believe the answer is:

behave

I'm a little stuck... Click here to teach me more about this clue!

'things and show one's breeding' is the definition.
I can't tell whether this defines the answer.

'live to own' is the wordplay.
'live' becomes 'be' ('be' can be a synonym of 'live').
'to own' becomes 'have' ('have' can be a synonym of 'own').
'be'+'have'='BEHAVE'

Can you help me to learn more?

(Other definitions for behave that I've seen before include "Handle" , "Act in a specified way" , "Act appropriately" , "Act properly" , "Spanish peninsula" .)

I've seen this clue in the Evening Standard.
