audio-video

The compound 'audio-video' is a modern technological term constructed from two classical Latin roots. 'Audio' derives from the verb 'audire', meaning 'to hear', which traces back to the Proto-Indo-European root h₂ew- (to perceive). 'Video' originates from 'videre', meaning 'to see', from the PIE root weid- (to see, to know). In the 20th century, these roots were revived as independent English combining forms to describe sound and visual technologies, respectively. Their combination into the hyphenated adjective 'audio-video' logically and directly describes systems or content that integrate both the auditory and visual senses, reflecting the dual-sensory experience of modern media.

Structure: audio (hearing) + video (seeing) audio: From Latin 'audire' (to hear). In English, it functions as a combining form meaning 'sound' or 'hearing'. video: From Latin 'videre' (to see). In English, it functions as a combining form meaning 'visual' or 'relating to sight'.
