Definition : In semiotics, a sign is anything that communicates a meaning that is not the sign itself to the interpreter of the sign.

The meaning can be intentional such as a word uttered with a specific meaning, or unintentional, such as a symptom being a sign of a particular medical condition.

Signs can communicate through any of the senses, visual, auditory, tactile, olfactory, or taste.
