Abstract
<jats:title>Abstract</jats:title> <jats:p>Plagiarism is intentionally or knowingly reusing words, works, or ideas from another source without proper, clear, and unambiguous acknowledgment. Although definitions of plagiarism vary across institutions, it is generally agreed that three criteria must be met for plagiarism to occur: the reuse of another original work, the absence of acknowledgment, and the author's intention to deceive. Given its nature, definition, and practice, plagiarism is inextricably linked to language, law, and technology. Although plagiarism is not exclusive to verbal language and also exists in films, music, or works of art, among others, it is predominantly expressed through language. Therefore, language plays a pivotal role in both producing and detecting plagiarism, making it a subject of applied linguistics. Plagiarism is often erroneously considered immoral, but not illegal. While cases of nonacademic plagiarism are more frequently brought to court due to its potential for financial remedies, instances of academic plagiarism tried by courts of law abound, particularly because plagiarism involves a breach of moral rights, the right to the integrity of the work. Due to its forensic nature, plagiarism detection and analysis are crucial in establishing plagiarism. Detection of plagiarism can be based on intuition, chance, or, more systematically, use of specialized software. However, these tools have limitations, such as relying on accessible databases, potentially misidentifying altered text, or misclassifying AI‐generated plagiarism. This entry defines plagiarism, explains its relation to language, law and technology, and explores plagiarism strategies and techniques to establish it.</jats:p>
