cell-phone

The term "cell-phone" is a modern compound that logically combines two established concepts. The first element, "cell," draws from its Latin root meaning a small compartment or room, which in the 1970s was applied to the hexagonal subdivisions of a cellular radio network, each served by its own transmitter. The second element, "phone," originates from the Greek word for voice or sound, long used in English to denote instruments of auditory transmission like the telephone. Thus, the word's literal construction as "cell-network voice device" perfectly captures its function as a portable telephone that operates by connecting to a network of geographically defined radio cells.

Structure: cell (small compartment) + phone (sound, voice) - cell: From Latin cella (small room, storeroom). In this compound, it refers to the small geographical area (cell) served by a single base station in a cellular network. - phone: From Greek phōnē (sound, voice). In this compound, it functions as a combining form meaning an instrument for transmitting or receiving sound.
