The word 'videophone' is a modern compound, a portmanteau of two classical roots combined in the mid-20th century to describe a then-futuristic technology. The first element, 'video', originates from the Latin verb 'vidēre', meaning "to see," which is also the source of words like 'vision' and 'evidence'. The second element, 'phone', derives from the Greek noun 'phōnē', meaning "sound" or "voice," found in terms like 'telephone' and 'microphone'. The compound's logic is perfectly transparent: it literally denotes an instrument for "seeing sound" or, more accurately, a device that combines the visual capability of television with the audio communication of a telephone, creating a unified concept for synchronous audiovisual conversation.

Structure: video (relating to visual images) + phone (sound, voice) - video: From Latin 'vidēre' (to see). In English, it functions as a combining form meaning "relating to the recording, reproducing, or broadcasting of visual images." - phone: From Greek 'phōnē' (sound, voice). In English, it functions as a combining form meaning "an instrument using or connected with sound."
