IPA: /ˈteɪlˌpiːs/
KK: /ˈteɪlˌpis/
A part that is added to the end of something, often serving a specific function or decoration.
The violin's tailpiece holds the strings in place and contributes to the instrument's sound quality.
Tailpiece → It is formed from "tail" (from Old French *tail*, meaning the end or rear part) and "piece" (from Latin *pax*, meaning a part or section). The word "tailpiece" refers to a part that is at the end or a section that completes something.
Think of the 'end' ('tail') of something and a 'part' ('piece') that completes it — that's what a tailpiece is.
