Honorific expressions in Japanese grammar, also known as “keigo,” are a vital aspect of the language that enable speakers to demonstrate respect or politeness towards others. In Japanese culture, using the appropriate level of honorifics is essential for maintaining social harmony and showing respect for others’ positions, ages, and relationships. There are various levels of honorific expressions, such as “sonkeigo” (respectful language), “kensongo” (humble language), and “teineigo” (polite language). Mastering these expressions is crucial for effective communication in Japanese and fully understanding the subtleties of the language.
