Plural of aberration; instances of deviating from what is normal, expected, or usual, or things that exhibit such deviation.
From 'aberration' (from Latin 'aberratio') + '-s' (plural marker). 'Aberration' itself emerged in English in the 17th century, becoming commonplace in science and medicine.
Aberrations are everywhere in physics, psychology, and biology—from optical aberrations (blurry images) to mental health aberrations (unusual thoughts)—the word became indispensable because deviation from normal is one of science's core interests.
