Root Explanation
Stimulant → It is formed from "stimulare" (meaning to incite or urge on) and the suffix "-ant" (indicating an agent or something that performs an action). The word "stimulant" refers to something that incites or urges on activity or excitement.
Memory Tip
Think of something that 'urges on' or 'incites' activity — that's what a stimulant does.
