Root Explanation

Preprocess → It is formed from "pre-" (meaning before) and "process" (from Latin "processus", meaning a series of actions or steps). The word "preprocess" means to perform actions or steps before the main process begins.

Memory Tip

Think of doing something 'before' ('pre-') the main 'series of actions' ('process') — that's what preprocess means.
