'typically-divided' originates from the combination of 'typical' and 'divide', where 'typical' means 'characteristic of a particular person or thing' and 'divide' means 'to separate into parts'.

'typically-divided' evolved from the combination of the words 'typical' and 'divide', which have been used in English since the late Middle Ages.

Initially, it meant 'characteristically separated', and this meaning has largely remained the same in modern usage.
