'modernly-divided' originates from the combination of 'modernly' and 'divided', where 'modernly' is derived from 'modern', meaning 'of the present or recent times', and 'divided' from 'divide', meaning 'to separate into parts'.

'modernly' evolved from the Middle English 'moderne', which came from the Latin 'modernus', and 'divided' from the Old French 'diviser', which came from the Latin 'dividere'.

Initially, 'modernly' meant 'in a modern manner', and 'divided' meant 'separated into parts'. Together, they convey the idea of being separated in a contemporary way.
