'typically-joined' originates from the combination of 'typical' and 'joined', where 'typical' means 'usual' and 'joined' means 'connected'.

'Typically' and 'joined' have been used separately in English for centuries, but their combination into 'typically-joined' is a modern usage to describe a common association.

Initially, 'typical' and 'joined' were used separately, but over time, their combination has come to describe a frequent or usual connection.
