This document provides an overview of pragmatics from a lecture. It defines pragmatics as the study of speaker meaning, contextual meaning, and how more is communicated than what is said. It discusses key concepts in pragmatics including invisible meaning, context, deixis, reference, inference, anaphora, presupposition, speech acts, and politeness. Politeness involves face-saving acts that minimize threats to people's self-image and independence or connection to others. The appropriate interpretation of language depends on context and can differ across cultures.
