Secretary Girl In The Past

The term is derived from the Latin word secernere, "to distinguish" or "to set apart," the passive participle (secretum) meaning "having been set apart," with the eventual connotation of something private or confidential, as with the English word secret. A secretarius was a person, therefore, overseeing business confidentially, usually for a powerful individual (a king, pope, etc.). As the duties of a modern secretary often still include the handling of confidential information, the literal meaning of their title still holds true.
Origin
Since the Renaissance until the late 19th century, men involved in the daily correspondence and the activities of the mighty had assumed the title of secretary.
