What is the term for acts that violate criminal law?

The term that encompasses acts violating criminal law is "crime." A crime can be defined as an action or the commission of an act that is prohibited or punishable by law. This term covers a wide range of unlawful acts, ranging from minor offenses to serious felonies.

The other terms mentioned have more specific meanings within the context of criminal law. For example, a felony refers specifically to a serious crime, typically punishable by more than one year in prison, while a violation is a general term that can refer to breaking laws but is often used for less severe offenses. An infraction usually refers to a minor violation of rules or regulations, often resulting in a small fine rather than imprisonment. Thus, while all these terms relate to unlawful conduct, "crime" is the most comprehensive term that collectively refers to any act that violates criminal law.
