The concept of crime occupies a central place in legal, linguistic, and social studies, as it reflects actions that violate established norms and threaten public order. In academic discourse, this concept is primarily expressed through the terms “crime” and “offense”, along with their numerous derivatives. Each of these terms carries specific semantic, pragmatic, and stylistic nuances that shape how unlawful behavior is described and interpreted in various contexts. This study focuses on expressing the CRIME concept through the lexical units “crime”, “offense”, and their derivations, examining their meanings, functions, and usage patterns in modern English. Understanding these terms not only contributes to a clearer interpretation of legal texts, but also enhances cross-disciplinary analysis involving linguistics, criminology, and communication studies.
