Root Explanation

Acceleration → It is formed from "ad-" (meaning to) and "celerare" (meaning to hasten or make swift). The word describes the process of making something faster or increasing its speed.

Memory Tip

Think of 'to' ('ad-') make something 'swift' ('celerare') — that's why acceleration means to increase speed.
