Root Explanation

Nephelinite is derived from "nephelin" (from Greek "nephelē", meaning cloud) and the suffix "-ite" (used to denote minerals or rocks). The term refers to a type of volcanic rock that is rich in nepheline, which is a mineral that can appear cloudy or glassy in appearance, resembling clouds.

Memory Tip

Think of 'cloud' ('nephelē') to remember that 'nephelinite' refers to a rock that has a cloudy appearance due to its mineral content.
