A person who uses a product, service, or system. In computing, it usually means someone who interacts with software or a website.
From 'use' + '-er' (one who does), formed in Middle English. It became especially common in technology contexts in the 1900s.
In tech, calling people 'users' shifts attention from who they are to what they do with a system. That’s why modern design talks more about 'people' and 'customers'—to remind us there’s a real life behind every click.
