Root Explanation

Greensand is formed from "green" (from Old English "grene", meaning of the color green) and "sand" (from Old English "sand", meaning loose granular material). The word "greensand" refers to a type of sand that has a greenish color, often due to the presence of minerals such as glauconite.

Memory Tip

Think of the color 'green' ('grene') and 'sand' as loose material — greensand is simply sand that has a greenish hue.
