'modernly-performed' originates from the combination of 'modernly' and 'performed', where 'modernly' is derived from 'modern', meaning 'of the present or recent times', and 'performed' is derived from 'perform', meaning 'to carry out an action or task'.

'modernly' evolved from the Middle English 'moderne', which came from the Latin 'modernus', and 'performed' evolved from the Old French 'parformer', which came from the Latin 'performare'.

Initially, 'modernly' meant 'in a modern way', and 'performed' meant 'to carry out', and these meanings have largely remained the same in modern usage.
