The word 'webpage' is a modern compound formed in the late 20th century from two pre-existing English words. 'Web' is a metaphorical extension of its original meaning of a woven fabric or interconnected structure, famously applied by Tim Berners-Lee to the 'World Wide Web' to describe its interconnected nature. 'Page' retains its long-standing meaning of a single side of a sheet in a book or a document. The compound elegantly conceptualizes a discrete unit of content on the internet as analogous to a page within the vast, interconnected 'web' of information, blending a physical metaphor with digital reality.

Structure: web (network) + page (document) - web: From Old English webb (woven fabric, web). In this compound, it functions as a modifier meaning "of or relating to the World Wide Web." - page: From Latin pagina (a sheet, page, leaf). In this compound, it functions as the core noun meaning a discrete unit of information or document.
