n. sound, especially when recorded, transmitted, or reproduced
adj. relating to sound or its reproduction
The word audio comes directly from Latin audire, meaning "to hear." It entered English in the early 20th century, primarily in technical contexts related to sound recording and broadcasting. The root aud- is widely used in English (e.g., audience, auditory) and retains its core meaning of hearing. The simplicity of audio as a standalone morpheme makes it easy to recognize in compound terms like audiobook or audiovisual.
