The word 对讲机 (duìjiǎngjī), meaning "walkie-talkie" or "intercom", is formed through a logical, descriptive compounding of three morphemes: 对 (duì) implies "mutual" or "two-way", 讲 (jiǎng) means "to speak", and 机 (jī) denotes "machine" or "device". Thus, the term literally and transparently describes a "mutual-speak-machine", or a device for two-way verbal communication, efficiently capturing its core function through its morphological structure.
