Iconic signs, however, "may or may not have it depending on how they’re used ... iconicity, therefore, is the most probable road that our ancestors took into language". Using a niche-construction view of human evolution, Bickerton has hypothesized that human ancestors used iconic signs as recruitment signals in the scavenging of dead ...
Typographical symbols and punctuation marks are marks and symbols used in typography with a variety of purposes such as to help with legibility and accessibility, or to identify special cases. This list gives those most commonly encountered with Latin script. For a far more comprehensive list of symbols and signs, see List of Unicode characters.
Symbols are complex, and their meanings can evolve as the individual or culture evolves. When a symbol loses its meaning and power for an individual or culture, it becomes a dead symbol. When a symbol becomes identified with the deeper reality to which it refers, it becomes idolatrous as the "symbol is taken for reality."
Icons are those signs that signify by means of similarity between sign vehicle and sign object (e.g. a portrait or map), indices are those that signify by means of a direct relation of contiguity or causality between sign vehicle and sign object (e.g. a symptom), and symbols are those that signify through a law or arbitrary social convention.
For example, in the ASL sign HOUSE, the hands are flat and touch in a way that resembles the roof and walls of a house. [2] [note 1] However, many other signs are not iconic, and the relationship between form and meaning is arbitrary. Thus, while Hockett did not account for the possibility of non-arbitrary form-meaning relationships, the ...
Saussure suggests that the meaning of a sign is arbitrary, in effect; there is no link between the signifier and the signified. [31] The signifier is the word or the sound of the word and the signified is the representation of the word or sound.
Many signs have metaphoric mappings as well as iconic or metonymic ones. For these signs there are three-way correspondences between a form, a concrete source and an abstract target meaning. The ASL sign LEARN has this three-way correspondence. The abstract target meaning is "learning". The concrete source is putting objects into the head from ...
Most signs operate on several levels—iconic as well as symbolic and/or indexical. This suggests that visual semiotic analysis may be addressing a hierarchy of meaning in addition to categories and components of meaning. As Umberto Eco explains, "what is commonly called a 'message' is in fact a text whose content is a multilevel discourse". [2]
