Root Explanation

Immobilizer → It is formed from "in-" (meaning not) and "mobilis" (from Latin, meaning movable) and "-izer" (a suffix indicating an agent or something that performs an action). The word "immobilizer" refers to something that makes something else not movable or unable to move.

Memory Tip

Think of 'not' ('in-') allowing something to be 'movable' ('mobilis') — an immobilizer is something that prevents movement.
