secretarial

The word 'secretarial' has a lineage deeply rooted in the concept of confidentiality. Its core, 'secret', originates from the Latin secretus, meaning 'separated' or 'set apart', which evolved to signify something private or hidden. The role of a secretary was historically one entrusted with private and confidential matters, such as correspondence and records. The addition of the Latin adjectival suffixes -arius and -alis transforms this noun into an adjective, 'secretarial', literally meaning 'pertaining to the keeper of secrets', which evolved to describe the general administrative duties and office work associated with the position.
