Derek Bickerton has posited that iconic signs, both verbal and gestural, were crucial in the evolution of human language. Animal communication systems, Bickerton has argued, are largely composed of indexical (and, occasionally, iconic) signs, whereas in human language, "most words are symbolic, and ... without symbolic words we couldn’t have language".
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 ...

(Peirce's sign theory concerns meaning in the broadest sense, including logical implication, not just the meanings of words as properly clarified by ...
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.

A sign can be a word, sound, a touch or visual image. Saussure divides a sign into two components: the signifier, which is the sound, image, or word, and the signified, which is the concept or meaning the signifier represents. For Saussure, the relation between the signifier and the signified is arbitrary and conventional.
Central to what de Saussure says about words are two related statements: First, he says that "the sign is arbitrary". He considers the words that we use to indicate things and concepts could be any words – they are essentially just a consensus agreed upon by the speakers of a language and have no discernible pattern or relationship to the thing.
Symbolic communication includes gestures, body language and facial expressions, as well as vocal moans that can indicate what an individual wants without having to speak. Research argues that about 55% of all communication stems from nonverbal language. [2] Symbolic communication ranges from sign language to braille to tactile communication skills.
