In semiotics, a modality is a particular way in which information is to be encoded for presentation to humans, i.e. to the type of sign and to the status of reality ascribed to or claimed by a sign, text, or genre. It is more closely associated with the semiotics of Charles Peirce (1839–1914) than Ferdinand de Saussure (1857–1913) because meaning is conceived as an effect of a set of signs. In the Peircean model, a reference is made to an object when the sign (or representamen) is interpreted recursively by another sign (which becomes its interpretant), a conception of meaning that does in fact imply a classification of sign types.
