Did you know that some materials are nondiffusible?

Root Explanation

Nondiffusible → It is formed from "non-" (meaning not) and "diffusible" (from Latin "diffundere", meaning to spread out or scatter). The word "nondiffusible" means not able to spread out or scatter.

Memory Tip

Think of 'non-' meaning not, and 'diffusible' meaning able to spread. So, nondiffusible describes something that cannot spread out.
