Deviant & Deviate

Deviant and deviate share a common root (the Latin deviare “to wander off the road, swerve, deviate”) and have some similarities in meaning, but they differ in notable ways. Deviant has functioned in English as an adjective (since the 15th century) and as a noun (since the early 20th century), in each case with a sense that suggests a straying from an accepted norm or from what is considered standard behavior. In contrast to deviant’s socially prescriptive connotations, the verb deviate often implies a less judgmental sense of swerving from the usual way (as in “he never deviated from his routine of drinking coffee with breakfast.”)
