'scheduled-update' originates from the combination of 'schedule' and 'update', where 'schedule' comes from Latin 'schedula', meaning 'a small slip of paper', and 'update' is derived from 'up' and 'date', meaning 'to bring up to date'.

'schedule' changed from the Old French word 'cedule' and eventually became the modern English word 'schedule'. 'Update' evolved from the combination of 'up' and 'date' in modern English.

Initially, 'schedule' meant 'a list or plan', and 'update' meant 'to bring up to date'. Together, they evolved to mean 'a planned update'.
