This document discusses linguistic politeness and various models of politeness. It defines politeness as linguistic structures that express a speaker's attitude in a pragmatic rather than semantic way. Interactions involve both conveying meaning and observing social rules shaped by distance and closeness between participants. Watts groups standard behaviors like "thank you" and address terms under the term "politic behavior" which society expects in certain situations. The document outlines politeness models including Lakoff's social norm model, Leech's conversational maxim model, Fraser and Nolen's conversational contract model, and Brown and Levinson's face theory of politeness involving face-threatening acts and strategies to maintain one's own and others' positive and negative face.
