Semiotics is the study of signs and symbols and how they create meaning. It explores how we interpret various forms of communication, from language to images. For example, a traffic light uses colors to convey messages: red means stop, while green means go. This system of signs helps us understand and navigate our world. In semiotics, there are three main components: the sign, which is the symbol itself; the signifier, which is the form the sign takes; and the signified, which is the concept it represents. By analyzing these elements, we can better understand how meaning is constructed in different contexts, such as art, literature, and advertising.
