Part of speech: noun

Definitions

1. A rare mineral that consists of boron, aluminum, and silicon, typically occurring in metamorphic rocks, where it forms distinctive crystal shapes and displays various colors

3. A mineral composed of boron, aluminum, and silicon found mainly in metamorphic rocks, noted for its unique crystal formation and varied hues

Etymology: The mineral's name comes from the Ancient Greek "axínē", meaning "axe" or "adze", and the name refers to its shape. Axinite crystals are flat, thin and sharp-edged, so they look like little blades, and early mineralogists named the stone for that resemblance. The Greek word was taken into French as "axinite", and the English form follows that French coinage. The ending "-ite" is the standard suffix that mineralogists have long used to name minerals, as in "haematite" or "magnesite". Put together, the name is simply a description of the crystal's form, with the suffix added to mark it as a mineral rather than a tool.
