Politeness in language use within the teaching and learning process of Indonesian language is a fundamental aspect that supports effective educational communication between teachers and students. Polite language reflects respect, ethical awareness, and mutual appreciation, while also functioning as a means of character formation and the development of a healthy academic culture. In the classroom context, linguistic politeness is not limited to word choice, but also encompasses intonation, speech structure, and the appropriateness of language use in relation to social roles and communicative situations.

Through Indonesian language instruction, politeness in language is systematically taught and practiced as an integral part of comprehensive language competence. Teachers serve as role models in the use of proper and polite language, while students are guided to communicate effectively, respectfully, and responsibly. Thus, linguistic politeness in the teaching and learning process not only enhances the quality of classroom interaction but also contributes to the development of ethical and socially responsible language behavior in broader social contexts.
