The term "illusion" is most commonly understood as a false perception of an object or event. This definition highlights that an illusion involves a discrepancy between how something appears and how it actually is. For instance, a mirage is a well-known example of an illusion where the observer perceives water on a hot road, although no water is present.

Illusions can occur in various contexts, including visual, auditory, and cognitive senses, demonstrating how our mind can be tricked into interpreting perceptions that do not align with reality. This understanding is fundamental in psychology, art, and even everyday life scenarios where people misinterpret stimuli.

In contrast, describing an illusion as a fact, a commonly accepted reality, or an undeniable truth does not accurately capture the essence of what an illusion represents. These alternatives suggest an acceptance of the perception as reality, which contradicts the very nature of an illusion wherein the perceived object or event is misleading or deceptive.
