Semiotics, also called semiotic studies or semiology, is the study of cultural sign processes (semiosis), analogy, metaphor, signification and communication, signs and symbols. Semiotics is closely related to the field of linguistics, which in its part, studies the structure and meaning of language more specifically. Semiotics is usually divided into three branches, which include:
* 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
Semiotics is frequently seen as having important anthropological dimensions; for example, Umberto Eco proposes that every cultural phenomenon can be studied as communication. However, some semioticians focus on the logical dimensions of the science. They examine areas belonging also to the natural sciences – such as how organisms make predictions about, and adapt to, their semiotic niche in the world (see semiosis). In general, semiotic theories take signs or sign systems as their object of study: the communication of information in living organisms is covered in biosemiotics or zoosemiosis.
