Aberration comes from Latin aberrātiō, meaning "a wandering away, distraction", derived from aberrāre, combining ab-  ("away from") and errāre ("to wander, stray, err").  Its core idea, rooted in movement from a path, entered English in the 16th century, first used in a theological sense before expanding to describe deviations from norms, mental states, optical focuses, or celestial positions (astronomical aberration). 

According to the Oxford English Dictionary (OED), the noun "aberration" was first used in English in the late 1500s, with the earliest evidence found in 1588, in the writings of R. Some, meaning a wandering or straying.  By the 1730s, it gained the meaning of "deviation from the normal type" (e.g., in optics), and by the 18th century, it was used in astronomy (aberration of light) and for mental/moral deviations. 

Examples of "aberration" used in a sentence: 
"Typical aberrations that can impact imaging performance include astigmatism, chromatic aberration, and spherical aberration." 
"The student sitting in the back of the classroom spoke up, which was an aberration from her unusual introverted behavior."
