A sign is an entity which signifies another entity. A natural sign is an entity which bears a causal relation to the signified entity, as thunder is a sign of storm. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence. (Contrast a symbol which stands for another thing, as a flag may be a symbol of a nation)

The way in which a sign signifies is a topic in philosophy of language, see also Meaning (linguistic). The musical instrument is spelled Cymbal. A symbol is something --- such as an object, Picture, written word a sound a piece Philosophy of language is the reasoned inquiry into the nature origins and usage of Language. This article is about meaning as it is studied in the discipline of linguistics

Any given signifier or symbol is dependent upon that which is intended, expressed, or signified in a semiotic relationship of signification, significance, meaning, or import. Semiotics, semiotic studies, or semiology is the study of sign processes (semiosis or signification and communication signs and Symbols both In Semiotics, the meaning of a sign is its place in a Sign relation, in other words the set of roles that it occupies within a given sign relation Thus, for example, people may speak of the significance of events, the signification of characters, the meaning of sentences, or the import of a communication. These different relationships that exist between sorts of signs can help people and sorts of things that are signified can be called the modes of signification.

The range of uses of signs are varied. They might include: the indication or mark of something, a display of a message, a signal to draw attention, evidence of an underlying cause (for instance, the symptoms of a disease are signs of the disease), a character for a mathematical operation, a body gesture, etc.

Nature of signs

Semiotics, epistemology, logic, and philosophy of language are concerned about the nature of signs, what they are and how they signify. Semiotics, semiotic studies, or semiology is the study of sign processes (semiosis or signification and communication signs and Symbols both Epistemology (from Greek επιστήμη - episteme, "knowledge" + λόγος, " Logos " or theory of knowledge Philosophy of language is the reasoned inquiry into the nature origins and usage of Language. The nature of signs and symbols and significations, their definition, elements, and types, is mainly established by Aristotle, Augustine, and Aquinas. Aristotle (Greek Aristotélēs) (384 BC – 322 BC was a Greek philosopher a student of Plato and teacher of Alexander the Great. According to these classic sources, significance is a relationship between two sorts of things: signs and the kinds of things they signify (intend, express or mean), where one term necessarily causes something else to come to the mind. Distinguishing natural signs and conventional signs, the traditional theory of signs sets the following threefold partition of things:

There are things that are just things, not any sign at all;
There are things that are also signs of other things (as natural signs of the physical world and mental signs of the mind);
There are things that are always signs, as languages (natural and artificial) and other cultural nonverbal symbols, as documents, money, ceremonies, and rites.

Thus there are things which may act as signs without any respect to the human agent (the things of the external world, all sorts of indications, evidences, symptoms, and physical signals), there are signs which are always signs (the entities of the mind as ideas and images, thoughts and feelings, constructs and intentions); and there are signs that have to get their signification (as linguistic entities and cultural symbols). So, while natural signs serve as the source of signification, the human mind is the agency through which signs signify naturally occurring things, such as objects, states, qualities, quantities, events, processes, or relationships. Human language and discourse, communication, philosophy, science, logic, mathematics, poetry, theology, and religion are only some of fields of human study and activity where grasping the nature of signs and symbols and patterns of signification may have a decisive value. A language is a dynamic set of visual auditory or tactile Symbols of Communication and the elements used to manipulate them Discourse (L discursus, "running to and from" means either "written or spoken communication or debate" or "a formal discussion Communication is the process of conveying information from a sender to a receiver with the use of a medium in which the communicated information is understood the same way Philosophy is the study of general problems concerning matters such as existence knowledge truth beauty justice validity mind and language Science (from the Latin scientia, meaning " Knowledge " or "knowing" is the effort to discover, and increase human understanding Logic is the study of the principles of valid demonstration and Inference. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and Theology is the study of a god or the gods from a religious perspective A religion is a set of Tenets and practices often centered upon specific Supernatural and moral claims about Reality, the Cosmos
