Etymology

Origin of conviction

First recorded in 1400–50; late Middle English, from Late Latin convictiōn-, stem of convictiō “proof (of guilt)” from convict(us) “convinced, conquered” (past participle of convincere; see convince) + -iō -ion ( def. )

Explanation

A conviction is something certain: a judgment of guilty in court and a strong belief are both convictions. In the legal world, when a judge or jury convicts someone of a crime — finding them guilty — this is called a conviction. Prosecutors try to get convictions, and defense attorneys try to prevent them. Also, convictions are beliefs — principles. The United States was founded on many convictions, such as the belief in free speech and separation of church and state. When you have a conviction, you're certain of something.
