Etymology

Origin of deviate

First recorded in 1625–35; from Late Latin dēviātus “turned from the road,” past participle of dēviāre “to stray, turn from the road,” from Latin dē- de- + vi(a) “road, way” + āre, infinitive verb suffix

Explanation

If something turns off course or is diverted, it deviates from the expected or the norm. Deviating from explicit recipe directions is never a good idea, unless you want inedible food or a kitchen fire. The verb deviate can refer to divergence from a predicted path or road ("the airplane's route deviated from the flight plan"), but it can also refer to a divergence from normal behavior or expectations. When women demanded the right to vote, their behavior was considered shocking and deviated from the expectations of the time.
