Etymology
The word 'protocol' originates from the Late Latin protocollum, which referred to the first leaf of a papyrus roll glued to the manuscript, containing the date and contents. This term was borrowed from the Greek prōtokollon, a compound of prōtos ("first") and kolla ("glue"). The semantic journey moved from a physical glued sheet containing authentication details to the formal introductory formulas and preliminary records in medieval documents. This sense of an official formula or record evolved into the modern meanings of diplomatic etiquette and formal procedural rules, capturing the concept of an original, binding framework for conduct.
