'incorrectly-scheduled' originates from the combination of 'incorrectly' and 'scheduled'. 'Incorrectly' comes from the Latin 'incorrectus', where 'in-' meant 'not' and 'correctus' meant 'set right'. 'Scheduled' comes from the Latin 'schedula', a diminutive of 'scheda', meaning 'a strip of papyrus'.

'incorrectly' changed from the Latin word 'incorrectus' and eventually became the modern English word 'incorrectly'. 'Scheduled' evolved from the Latin 'schedula' through Old French 'schedule', and eventually became the modern English word 'scheduled'.

Initially, 'incorrectly' meant 'not set right', and 'scheduled' meant 'a list or plan'. Over time, 'incorrectly-scheduled' evolved to mean 'scheduled in a wrong or inappropriate manner'.
