Technological advances, especially in the world of social networking, can indirectly influence language use when interacting with interlocutors. Interacting via social media also uses language. Politeness in language is an important thing that speakers can use in communicating so that the person they are talking to does not feel pressured, cornered or offended. Politeness is also needed in responding to news. Thousands and even millions of news are circulating on social media. Not all of the news is true. There is also fake news or hoaxes. This fake news will target all groups, including mothers. Mothers are a group of people who are vulnerable to information. The Master of Linguistics Study Program at the Faculty of Cultural Sciences, apart from teaching and developing language knowledge, is also committed to educating the public in language on social media, especially language politeness in responding to fake news. For this reason, community service activities in 2023 are focused on responding to fake news on social media in the women’s environment of Caturtunggal and Terban Districts.
