Root Explanation

Staurolite is derived from the Greek "stauros" (meaning cross) and "lithos" (meaning stone). The word refers to a mineral that often forms in a cross-like shape, hence its name.

Memory Tip

Imagine a stone ('lithos') that looks like a cross ('stauros') — that's why staurolite is named for its cross-shaped appearance.
