Index

Definition

An index is a type of sign that refers to its object in a direct, causal way, often indicating something that is physically or conceptually connected. This relationship can be based on a cause-and-effect connection, such as smoke indicating fire, or a more abstract association, such as a weather vane pointing in the direction of the wind. Understanding indices is key to interpreting signs and meanings within communication and media.
