Violation of lexical norms in primary school textbooks is a serious problem and negatively affects the development of students' language skills. Also, violations of lexical norms in textbooks weaken children's thinking and communication skills. Therefore, special attention should be paid to the lexical norms of the language when preparing textbooks, and each word and expression should be selected purposefully. Teachers should be provided with methodological support and their language teaching skills should be improved. By taking these steps, correct language habits can be formed at the primary education level and support can be provided for the development of literary language in the future.
