What does deviant mean?
Deviant functions both as an adjective and a noun, describing anything — or anyone — that strays from established norms. As an adjective, it characterizes behavior, attitudes, or data points that diverge from what is standard, typical, or socially sanctioned: a deviant reading on a gauge, a deviant subculture, or deviant conduct in an experiment. As a noun, it refers to a person whose behavior differs markedly from societal expectations, though this use frequently carries pejorative weight, especially in moral or criminal discourse. The word is central to sociology and criminology, where 'deviance' names the academic study of rule-breaking behavior, and scholars often treat deviation from norms as neutral or even socially productive rather than merely pathological. In casual usage, however, calling someone a deviant is strongly condemnatory, so writers should be mindful of tone. Its Latin roots — literally 'to turn aside' — capture the core idea of veering off the expected path.
Departing from what is considered normal, acceptable, or expected, especially with reference to behavior or standards.

Neutral in technical/statistical contexts; often negative when describing people.
A person whose behavior differs markedly from what is considered socially or morally acceptable.

Standard plural for the noun form referring to multiple persons who deviate from norms.
"Sociologists study how societies label certain individuals as deviants."
In statistics, a 'deviant' is just a data point far from the mean — but in society, it's often someone who simply refuses to fit.

Etymology of deviant
Deviant derives from the Latin verb 'deviare', meaning 'to turn aside' or 'to stray from the road', formed from 'de-' ('away from') plus 'via' ('way' or 'road'). It entered English in the late Middle Ages via Late Latin 'devians', the present participle of 'deviare', initially appearing in theological and philosophical texts before broadening into general and later sociological usage. It shares its Latin root with related English words such as 'deviate', 'deviation', 'devious', and 'obviate'.
