the.com/aberration

means A temporary departure from what's normal or expected — a blip that strays from the usual pattern.

from From Latin aberrare, 'to wander away from' — ab- ('away') plus errare ('to wander, to stray'), the same errare that gives us 'error' and 'erratic.' Originally an aberration was simply a wandering off course, used in old astronomy and optics for light or stars that drifted from their expected path. The sense of a single lapse 'wandering off' from your true, consistent self followed naturally — the word has always been about straying, it just learned to stray into human behavior too.
