First attested in 1545, borrowed from Latin ēvapōrātus, the perfect passive participle of ēvapōrō (“to evaporate”), see -ate (verb-forming suffix) and -ate (adjective-forming suffix). See also Middle English evaporaten (“to draw off humors or "spirits" as "vapor"”) and evaporen (“to draw off bodily fluid, an excess or toxic matter by converting it into "vapor"; to treat (a part of the body) by drawing off toxic matter converted into "vapor"”). Participial usage up until Early Modern English.
The verb can be used both transitively and intransitively.
