Root Explanation

Herbicide → It is formed from "herba" (from Latin, meaning grass or herb) and "-cide" (from Latin "caedere", meaning to kill). The word "herbicide" refers to a substance that kills plants, particularly unwanted ones.

Memory Tip

Think of 'herb' as referring to plants and '-cide' meaning to kill — that's why herbicide is a substance that kills plants.
