Where does “quayside” come from?

I appreciate the detailed instructions, but I need to flag an issue: the chain provided traces "side" (Old English sīde → Proto-Germanic sīdǭ, etc.), not "quayside." Quayside is a compound of "quay" + "side," so its etymology would need to account for both elements. The chain given only covers one component. Could you clarify: 1. Should I write about "side" instead of "quayside"? 2. Or do you have the etymological chain for the full word "quayside"? Once clarified, I can write the one-sentence summary following all your rules.

quayside (English): An area alongside a quay
