Root Explanation

Hydrogen → It is formed from "hydro-" (from Greek "hydor", meaning water) and "-gen" (from Greek "genes", meaning creator or former). The word "hydrogen" means creator of water, as it is a key component in the formation of water molecules.

Memory Tip

Think of 'water' ('hydor') being created ('-gen') — that's why hydrogen is known as the creator of water.
