Usage
What does arrest mean? To arrest someone is to seize them or take them into custody with authority. Related to that, an arrest is the act of police or other law enforcement officials detaining someone suspected of committing a crime when there is probable cause. Arrest can also more generally mean to attract and engage, such as with attention or sight. For example, a loud clap of thunder might arrest your attention for a moment, if you weren’t expecting it. Arrest also means to slow or stop, such as with progress or growth. You might, for example, arrest the growth of a plant by keeping it in the dark while continuing to water it. Such an arrest could lead the plant to die. Example: You are under arrest for conspiracy to commit grand theft auto.

Etymology
Origin of arrest
1275–1325; (v.) Middle English aresten < Anglo-French, Middle French arester, < Vulgar Latin *arrestāre to stop ( see ar-, rest 2); (noun) Middle English arest ( e ) < Anglo-French, Old French, noun derivative of v.
Explanation
To arrest someone is to put them in custody for breaking the law. If you face arrest, your criminal activities will be "at rest" because you'll be behind bars, or in jail. Arrest is both a noun and a verb. When you place a person "under arrest," you take them into custody and hold them so they can’t continue breaking the law. A police officer or other agent of the law will arrest a person often by physically taking them away. In addition to the legal meaning, arrest means "stop." To arrest motion is to stop a person or thing from moving.
