Azurite
Blue secondary copper carbonate hydroxide Cu₃(CO₃)₂(OH)₂.
Language and route: English via French azurite (Beudant) and azure, with medieval French and Arabic intermediaries ultimately associated with Persian lāžvard; exact intermediate route contested.

The name and its history
François Sulpice Beudant · 1824 name applied to an older blue copper mineral
- What does the word literally mean?
- Immediate linguistic route: English via French azurite (Beudant) and azure, with medieval French and Arabic intermediaries ultimately associated with Persian lāžvard; exact intermediate route contested. Earliest relevant language form supplied here: azur (azur), conventionally glossed ‘azure blue’. The literal sense is distinct from what the early name was used to classify.
- What did the original author mean?
- Beudant formalised an azure-colour designation for a mineral long familiar as a blue pigment or copper ore.
- Why was the name needed?
- Systematic mineralogists wanted to separate blue copper carbonate from other blue gemstones and minerals whose colour names were shared.
- What evidence supported the original concept?
- Colour and copper-ore association were evident; comparative chemistry and crystallography subsequently separated azurite from other blue copper species.
- How has geology changed the concept?
- Azurite can alter to malachite; the medieval blue word’s deeper history should not be mistaken for the author’s verified original linguistic intention.
