A linguistic error refers to a mistake made in the use of language, which can occur in speaking or writing. These errors can involve grammar, spelling, punctuation, or word choice, leading to confusion or miscommunication. Common examples include subject-verb agreement errors and incorrect verb tenses. Linguistic errors can be categorized into different types, such as syntax errors, which involve the arrangement of words, and morphological errors, which relate to the structure of words. Understanding these errors is essential for improving language skills and effective communication in various contexts, including education and professional settings.
