Root Explanation

Arrestant → It is formed from "arrest" (from Old French *arrest*, meaning to stop or seize) and "-ant" (a suffix used to form adjectives or nouns indicating an agent). The word "arrestant" refers to something that causes or is related to stopping or seizing.

Think of 'arrest' meaning to 'stop' something, and the '-ant' indicates it is an agent or something that does the action. So, an 'arrestant' is something that causes a stop.
