Etymology: "User" is a plain formation: the noun "use" with the agent suffix "-er," meaning one who uses something. It came into English from Middle English "usere," which was built the same way, and Scots "usar" and "uiser" share that origin, showing the word was formed independently across the English-speaking north and south. The sense of a person who interacts with or benefits from a product or service is a much later development. Older uses of the word were broad and general, covering anyone who made use of something, while the modern computing and consumer sense narrowed it to the person on the other end of a system or service.
