Semiotics, also called semiotic studies and including (in the Saussurean tradition) semiology, is the study of signs and sign processes (semiosis), indication, designation, likeness, analogy, metaphor, symbolism, signification, and communication. Semiotics is closely related to the field of linguistics, which, for its part, studies the structure and meaning of language more specifically. However, as different from linguistics, semiotics studies also non-linguistic sign systems. Semiotics is often divided into three branches:
Semantics: Relation between signs and the things to which they refer; their denotata, or meaning
Syntactics: Relations among signs in formal structures
Pragmatics: Relation between signs and the effects they have on the people who use them
