In plain English: A protocol is an agreed-upon set of rules that everyone follows to make sure things work smoothly and correctly.

Usage: In everyday usage, protocol refers to the established order of procedure or etiquette that governs social interactions and formal events. Do not confuse this with the official written record of a negotiation, which is technically called minutes or a memorandum.
To make a protocol of.
"The committee decided to establish a strict protocol for handling confidential data before sharing it with external partners."
In plain English: To protocol something means to follow a specific set of rules or procedures for doing it correctly.
"The diplomatic team will protocol the official greeting before the summit begins."
Usage: While "protocol" is frequently used as a verb to mean following established rules or procedures, this usage is considered incorrect by many style guides because it treats a noun as an action. Instead, use the phrase "follow protocol" or simply say that someone adhered to the required procedures.
The word protocol comes from the Byzantine Greek phrase for "the first sheet glued onto a manuscript," which originally referred to the introductory page listing contents or corrections in a book. It entered English via Middle French as a term for an official record or formal document, evolving into its current meaning of established rules or procedures.
