Did you know that some materials are considered fissile?

Really? What does that mean exactly?

Root Explanation

Fissile → It is formed from "fiss-" (from Latin "fissilis", meaning split or cleft) and the suffix "-ile" (meaning capable of). The word "fissile" refers to the capability of being split or divided, particularly in the context of nuclear materials.

Memory Tip

Think of something that is 'capable of being split' — 'fiss-' relates to splitting, and '-ile' indicates capability.
