The word 'webcam' is a modern portmanteau, a blend of two independent English words: 'web' and 'camera'. 'Web' evolved from the Old English 'webb' for a woven fabric, metaphorically extended in the late 20th century to mean the interconnected network of the World Wide Web. 'Camera' is a loanword from Latin meaning 'chamber' or 'vault', which came to denote a photographic device via the 'camera obscura'. The compound 'webcam' logically and literally describes a camera whose primary function is to transmit images over the web, a concise technological term born from the digital age.

Structure: web (network) + cam (camera) - web: (Origin: Old English webb; Role: Root/Combining form) Denoting a network, specifically the World Wide Web. - cam: (Origin: Shortened from camera; Role: Root/Combining form) Denoting a device for recording visual images.
