IPA: /ˈsaɪdˌpiːs/
KK: /ˈsaɪdˌpis/
A part that is located on the side of something, often used to support or enhance the main structure.
The chair has beautiful sidepieces that add to its design.
Sidepiece → It is formed from "side" (from Old English "side", meaning the lateral part of something) and "piece" (from Old French "piece", meaning a part or fragment). The term "sidepiece" refers to an additional or secondary part, often used in the context of a romantic partner who is not the primary partner.
Think of a 'side' as a lateral part and a 'piece' as a part of something — together, a sidepiece is an additional part or partner.
