Root Explanation

Bentonite is derived from the name of Fort Benton, Montana, where the clay was first identified, combined with the suffix '-ite' (meaning a mineral or rock). The word refers to a type of clay that is primarily composed of montmorillonite, a mineral that swells when wet.

Memory Tip

Think of Fort Benton as the place where this special clay was discovered, and remember that '-ite' indicates it's a mineral. This helps you connect the name 'bentonite' to the clay found there.
