Root Explanation

Inertial → It is formed from "inertia" (from Latin "inertia", meaning inactivity or lack of movement) and the suffix "-al" (meaning pertaining to). The word "inertial" refers to something that pertains to or is characterized by inertia, or the tendency to remain at rest or in uniform motion unless acted upon by an external force.

Memory Tip

Think of 'inertia' as a state of inactivity, and remember that 'inertial' describes something related to that state of not moving.
