Semiotics is the study of the processes of signs, which is any form of activity, behavior, or any process that involves signs, including the production of meaning. A sign is everything that communicates a meaning, which is not the sign itself, to the interpreter of the sign. To study this, semiotics is divided into three main branches: semantics, pragmatics, and syntactics. Among its antecedents is Saussure's theory of signs, which is also known as semiology.
