Etymology

The word 'postmark' is a transparent compound formed within English from the nouns 'post', referring to the mail system, and 'mark', meaning a sign or impression. The term 'post' itself has a long journey, originating from the Latin posita, the past participle of ponere (to place), which evolved to mean a fixed station or relay point for couriers in Medieval Europe. 'Mark' stems from the Proto-Germanic markō, conveying the concept of a boundary or a sign that delineates. Combined in the late 17th century, 'postmark' logically describes the official sign or impression placed by the postal service on a piece of mail, serving to record its passage through the system and often to invalidate the stamp.
