Root Explanation

Perturbation → It is formed from "per-" (meaning through or completely) and "turbare" (meaning to disturb or confuse), along with the suffix "-tion" (indicating the action or process). The word "perturbation" refers to the action of completely disturbing or unsettling something.

Memory Tip

Think of something being 'completely disturbed' ('per-') and 'confused' ('turbare') — that's what perturbation means.
