Semiotics (/ ˌ s iː m i ˈ ɒ t ɪ k s, ˌ s ɛ m -, - m aɪ -/ SEE -mee- OT -iks, SEM -, - my-) is the systematic study of sign processes and the communication of meaning. In semiotics, a sign is defined as anything that communicates intentional and unintentional meaning or feelings to the sign's interpreter.

Semiosis is any activity, conduct, or process that involves signs. Signs can be communicated through thought itself or through the senses. Contemporary semiotics is a branch of science that studies meaning-making and various types of knowledge.

The semiotic tradition explores the study of signs and symbols as a significant part of communications. Unlike linguistics, semiotics also studies non-linguistic sign systems. Semiotics includes the study of indication, designation, likeness, analogy, allegory, metonymy, metaphor, symbolism, signification, and communication.

Semiotics is frequently seen as having important anthropological and sociological dimensions. Some semioticians regard every cultural phenomenon as being able to be studied as communication. Semioticians also focus on the logical dimensions of semiotics, examining biological questions such as how organisms make predictions about, and adapt to, their semiotic niche in the world.

Fundamental semiotic theories take signs or sign systems as their object of study. Applied semiotics analyzes cultures and cultural artifacts according to the ways they construct meaning through their being signs. The communication of information in living organisms is covered in biosemiotics including zoosemiotics and phytosemiotics.
