'perfectly-done' originates from the combination of 'perfectly' and 'done', where 'perfectly' is derived from the Latin 'perfectus', meaning 'completed', and 'done' from Old English 'don', meaning 'to perform'.

'perfectly' evolved from the Latin 'perfectus' through Old French 'parfait', and 'done' from Old English 'don', eventually forming the modern English term 'perfectly-done'.

Initially, 'perfectly' meant 'completely' and 'done' meant 'performed', and together they have retained the meaning of 'executed with complete accuracy'.
