A small container that holds a tape used for recording or playing sound.
I found an old audiocassette of my favorite music from the 90s.
Audiocassette → It is formed from "audio" (from Latin "audire", meaning to hear) and "cassette" (from French "cassette", meaning a small box or case). The word "audiocassette" refers to a small case designed to hold audio recordings, allowing one to hear them.
Think of 'audio' meaning to 'hear' and 'cassette' as a 'small case' for holding recordings — that's how an audiocassette is a case for hearing audio.
