Semiotics and Semantic

Semiotics:

Semiotics, also called semiotic studies or 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 oflinguistics, which, for its part, studies the structure and meaning of language more specifically.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. In general, semiotic theories take signs or sign systems as their object of study: the communication of information in living organisms is covered inbiosemiotics or zoosemiosis.

Semantic:
Semantics is the study of meaning. It is a wide subject within the general study of language. An understanding of semantics is essential to the study of language acquisition (how language users acquire a sense of meaning, as speakers and writers, listeners and readers) and of language change (how meanings alter over time). It is important for understanding language in social contexts, as these are likely to affect meaning, and for understanding varieties of English and effects of style. It is thus one of the most fundamental concepts in linguistics. The study of semantics includes the study of how meaning is constructed,interpreted,clarified,obscured,illustrated, simplified negotiated, contradicted and paraphrased.
