phonebook

The word "phonebook" is a modern English compound, a straightforward combination of two ancient roots. The first element, "phone," is a clipping of "telephone," which itself derives from the Greek tēle- (far) and phōnē (sound, voice). The second element, "book," originates from the Old English bōc, related to the Proto-Germanic bōks (beech tree), as early Germanic peoples often wrote on beechwood tablets. The compound's logic is transparent: it is literally a "book" for "telephone" numbers. It emerged in the early 20th century alongside the widespread adoption of the telephone, serving as a directory to connect a person's name with their unique sound-transmitting address.

Structure: phone (sound/voice/telephone) + book (bound collection) - phone: From Greek phōnē, meaning "sound, voice." In this compound, it functions as a clipping of "telephone," representing the device or system for transmitting sound. - book: From Old English bōc, meaning "a written document, codex." In this compound, it functions as the head noun, indicating a bound collection of pages or information.
