'secretarial' originates from the word 'secretary', which comes from the Latin word 'secretarius', where 'secretus' meant 'secret'.

'secretarius' transformed into the Old French word 'secretaire', and eventually became the modern English word 'secretary'.

Initially, it meant 'one entrusted with secrets', but over time it evolved into its current meaning of 'a person employed to assist with correspondence and office tasks'.
