Root Explanation

Propellant → It is formed from "pro-" (meaning forward) and "pellere" (meaning to drive or push). The word "propellant" refers to a substance that drives or pushes something forward, particularly in the context of engines or rockets.

Memory Tip

Think of something that 'pushes forward' — 'pro-' means forward, and 'pellere' means to drive. This helps you remember that a propellant is a substance that drives something forward.
