What is an abberavition?

An "aberration" is a deviation from the expected or normal state, often used in various contexts such as science, literature, and psychology. In optics, it refers to the failure of a lens or mirror to bring light to a single focus, resulting in distorted images. In a broader sense, it can describe unusual behavior or events that diverge from typical patterns. Essentially, it signifies something that is atypical or anomalous.
