Semiotics is the study of signs and meaning-making. It examines how signs like words and images produce meaning, especially in cultural artifacts and communication. There are two main approaches: Saussure analyzed language as a system of signs composed of a signifier and signified. Peirce defined the sign as having a representamen, object, and interpretant, and classified signs as icons, indices, or symbols based on their relationship to their object. Semiotics provides tools to reveal hidden meanings in cultural texts and communication.
