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.
