Selected source glosses provide context, not a complete modern definition inventory

Learned borrowing from Ancient Greek κύανος (kúanos), a shade of blue variously described as similar to cornflower, copper carbonate, and lapis lazuli, Mycenaean Greek 𐀓𐀷𐀜 (ku-wa-no), possibly from Hittite [script needed] (kuwannan-, “a precious stone; copper; shade of blue”). Compare modern Greek κυανός (kyanós), also used for cyan.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
