Crime occupies a central place in criminal jurisprudence and serves as the foundation upon which criminal liability, punishment, and the administration of justice are built. This study provides a critical analysis of the concept of crime from jurisprudential and contemporary perspectives. It explores the nature, meaning, and essential elements of crime, examines various schools of thought, and discusses the relationship between crime, morality, and social order. The paper further investigates emerging forms of criminality and concludes that an effective understanding of crime requires an interdisciplinary approach integrating legal, philosophical, and sociological perspectives.
