A sign is a term traditionally defined as aliquid stat pro aliquo (something that represents something else). The term itself, separated from any specific meaning, is commonly used by semioticians as an all-encompassing and all-encompassing term.
Symbols, iconic signs, myths, texts, etc. are signs or systems of signs.
In other words, the sign is used as an umbrella term that houses a whole host of subtypes.
According to Ferdinand de Saussure, the sign represents a relative connection between signifier and signified (for example, between the acoustic image and its corresponding concept).
A modified version of this dyadic model was proposed by Louis Hjelmslev and adopted by many modern semioticians, especially in Europe.
In it, the sign represents a relative connection between the plan of expression and the plan of content.
In contrast to these models, Charles S. Peirce precedes a triadic concept: A sign is something that stands in place of something (called an object) in a way that creates another sign (its interpreter).
