In semiotics, a code is a set of conventions or sub-codes currently in use to communicate meaning. 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).

Ferdinand de Saussure (1857–1913) emphasised that signs only acquire meaning and value when they are interpreted in relation to each other. He believed that the relationship between the signifier and the signified was arbitrary. Hence, interpreting signs requires familiarity with the sets of conventions or codes currently in use to communicate meaning.
