IPA: /ˈkiːsaɪd/
KK: /ˈkwiːsaɪd/
The land next to a structure where ships are loaded and unloaded, often found in ports.
The children played by the quayside, watching the boats come and go.
Quayside is formed from "quay" (from Old French *kai*, meaning a platform or structure on the shore) and "side" (from Old English *sīde*, meaning the lateral part of something). The word "quayside" refers to the area or side of a quay, typically where ships dock and goods are loaded or unloaded.
Imagine a platform by the water where ships come to rest — that's the quayside, where the quay is the structure and the side is the area next to it.
