=== Semiotics ===
Semiotic theory is defined as a theory that seeks to describe the rhetorical significance of sign-making. The central idea of the theory is that a sign does not exist outside of a contextual experience, but it only exists in relation to other signs, objects, and entities. Therefore, the sign belongs to a larger system, and when taken out of context of other signs, is rendered meaningless and uncommunicable. The parts of a semiotic are divided into two parts: the material part of the sign is known as the ''form of expression,'' the meaning of the form of expression is known as ''form of content''.<ref name="Ehses, Lupton" /> In semiotic theory, the expression only has meaningful content when existing in a larger contextual framework.
