This document provides an introduction to semiotics, which is the study of signs and how meaning is generated in language and culture. It discusses several key concepts: 1) Signs can take the form of icons, indexes, or symbols. Icons resemble what they signify, indexes have a causal connection, and symbols are culturally learned. 2) Meaning is generated through the relationship between the signifier (sound or image) and the signified (concept). This relationship is arbitrary but grounded in social conventions. 3) Media messages use signs like camera shots, movements, and characters to convey meanings related to social relationships, intimacy, power, and emotions.
