The act of wandering; deviation, especially from truth or moral rectitude, from the natural state, or from a type.

A small periodical change of position in the stars and other heavenly bodies, due to the combined effect of the motion of light and the motion of the observer; called annual aberration, when the observer's motion is that of the earth in its orbit, and daily or diurnal aberration, when of the earth on its axis; amounting when greatest, in the former case, to 20.4'', and in the latter, to 0.3''. Planetary aberration is that due to the motion of light and the motion of the planet relative to the earth.

The convergence to different foci, by a lens or mirror, of rays of light emanating from one and the same point, or the deviation of such rays from a single focus; called spherical aberration, when due to the spherical form of the lens or mirror, such form giving different foci for central and marginal rays; and chromatic aberration, when due to different refrangibilities of the colored rays of the spectrum, those of each color having a distinct focus.

An optical defect resulting from design or fabrication error, e.g., coma, distortion, curvature of field that prevents the lens from achieving precise focus.

an error which is the result of misalignment with truth

A focusing error in the laser of a CD or DVD player, causing the disc to be misread.

a departure from rational thought or behavior. It means basically to err, to make mistakes, or more specifically to have fixed ideas which are not true. The word is also used in its scientific sense. It means departure from a straight line. If a line should go from A to B, then if it is aberrated it would go from A to some other point, to some other point, to some other point, to some other point, to some other point, and finally arrive at B. Taken in this sense, it would also mean the lack of straightness or to see crookedly as, for example, a man sees a horse but thinks he sees an elephant. Aberrated conduct would be wrong conduct, or conduct not supported by reason. When a person has engrams, these tend to deflect what would be his normal ability to perceive truth and bring about an aberrated view of situations which then would cause an aberrated reaction to them. Aberration is opposed to sanity, which would be its opposite. From the Latin, aberrare, to wander from; Latin, ab, away, errare, to wander.

A genetic or environmentally produced variation on the usual form of the species. For example very cold conditions can produce very dark forms of some species.

An individual with a clearly abnormal phenotype which occurs very rarely in a species. The unusual appearance of an aberration is usually the result of a freakish developmental abnormality or a rare mutation. To qualify as an aberration (rather than a form or morph), an individual must exhibit characteristics which are shown by no more than 0.01% of the members of its species. Aberrations are popularly referred to as "sports."

Aberration is a 1997 film directed by Tim Boxell, about a woman trying to escape from mutant lizards in the woods. The story is about mutated reptiles that live in isolation and breed to be strong. The lizards look like geckos and they live in a nest or bubble that is covered by slime.
