This document discusses linguistic politeness and face. It explains that Brown and Levinson theorized that all cultures have a need to be polite in order to maintain face, which refers to one's public self-image and expectations of how one wishes to be treated. The document outlines that people behave as if their face wants, or expectations of self-image, will be respected by others. It also discusses that speakers can perform face-threatening acts and face-saving acts in their language use. Face-threatening acts are those that damage another's face, while face-saving acts are ways of speaking that lessen threats to another's face.
