The second is a link to the article that details that symbol, using its Unicode standard name or common alias. (Holding the mouse pointer on the hyperlink will pop up a summary of the symbol's function.); The third gives symbols listed elsewhere in the table that are similar to it in meaning or appearance, or that may be confused with it;
Semiotics is the theory of symbols and falls in three parts; logical syntax, the theory of the mutual relations of symbols, logical semantics, the theory of the relations between the symbol and what the symbol stands for, and; logical pragmatics, the relations between symbols, their meanings and the users of the symbols."

Denotation refers to the meaning hidden in symbols or images. A denotation is "what we see" in the picture or what is "there" in the picture. [2] According to author Clive Scott, this is another way of saying that a photograph has both a signified and a referent, is both coded and encoded.
Thus, a symbol denotes by virtue of its interpretant. Its sign-action (semiosis) is ruled by habit, a more or less systematic set of associations that ensures its interpretation. For Peirce, every symbol is general, and that which we call an actual individual symbol (e.g., on the page) is called by Peirce a replica or instance of the symbol. [45]
The denotative meaning of a signifier is intended to communicate the objective semantic content of the represented thing. So, in the case of a lexical word, say "book", the intention is to do no more than describe the physical object. Any other meanings or implications will be connotative meanings.
French semiotician Roland Barthes used signs to explain the concept of connotation—cultural meanings attached to words—and denotation—literal or explicit meanings of words. [2] Without Saussure's breakdown of signs into signified and signifier, however, these semioticians would not have had anything to base their concepts on.
According to Ferdinand de Saussure (1857–1913), a sign is composed of the signifier [2] (signifiant), and the signified (signifié).These cannot be conceptualized as separate entities but rather as a mapping from significant differences in sound to potential (correct) differential denotation.
The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
