The word 'webmaster' is a modern English compound, formed in the late 20th century with the rise of the internet. The first element, 'web', is a shortening of 'World Wide Web', the system of interlinked hypertext documents. The second element, 'master', derives from the Latin magister, meaning 'chief, head, director, teacher', which conveys a sense of authority and control. When combined, the term literally means 'one who is in charge of the web', logically evolving to denote the person responsible for the development, maintenance, and administration of a website.

Structure: web (World Wide Web) + master (person in charge) - web: English (Modern English), functional role: a compound element referring to the World Wide Web. - master: English (from Old English mægester, via Latin magister), functional role: a noun-forming element meaning a person in authority or control.
