The term 'insistence on traditional correctness' can be summarized by the word purism, which is defined as a desire to maintain or restore a state of purity, especially in language. Purism is often associated with language, as it involves the attempt to remove foreign words and expressions from a language in order to maintain its original form. This concept is also applicable to other aspects of culture, such as art, music, and literature, where purists strive to preserve traditional forms and styles.
