The most common is one's spoken language, but the term can also be used to refer to any narrative form consider the color scheme of an image (e.g. red for danger), or the rules of a board game (e.g the military signifiers in chess).
Codes are rule-driven systems which suggest the choice of signifiers and their collocation to transmit the intended meanings in the most effective way. To that extent, codes represent a broad interpretative framework used by both addressers and their addressees to encode and decode the messages. Self-evidently, the most effective communications will result when both creator and interpreter use exactly the same code. Since signs may have many levels of meaning from the denotational to the connotational, the addresser's strategy is to select and combine the signs in ways that limit the range of possible meanings likely to be generated when the message is interpreted. This will be achieved by including metalingual contextual clues, e.g. the nature of the medium, the modality of the medium, the style, e.g. academic, literary, genre fiction, etc., and references to, or invocations of, other codes, e.g. a reader may initially interpret a set of signifiers as a literal representation, but clues may indicate a transformation into a metaphorical or allegorical interpretation.
For native speakers, the dominant symbolic code will be their language which is divided into spoken and written forms. The language will reflect (if not construct — see lexical words) the cultural reality and social codes diachronically. Distinctions of class or memberships of groups will be determined by the social identity each individual constructs through the way the language is spoken (i.e. with an accent or as a dialect) or written (i.e. in sentences or in SMS format), the place of residence (see Americanisms), the nature of any employment undertaken, the style of dress, and nonverbal behaviour (e.g. through differentiating customs as to the extent of private space, whether and where people may touch or stare at each other, etc.). The process of socialisation is learning to understand the prevailing codes and then deciding which to apply at any given time, i.e. acknowledging that there is sometimes an ideological quality to the coding system, determining levels of social acceptability, reflecting current attitudes and beliefs. This includes regulatory codes that are intended to control behaviour and the use of some signifying codes. The human body is a means of using presentational codes through facial expressions, gestures, and dress. So words spoken may change their connotation to unacceptable if accompanied by inappropriate nonverbal signs.
