Etymology

Origin of mist¹

First recorded before 900; (noun) Middle English, Old English; cognate with Dutch, Low German, Swedish mist; akin to Greek omíchlē “fog,” Russian mgla “mist,” Sanskrit megha “cloud”; (verb) Middle English misten, Old English mistian, derivative of the noun

Origin of mist.²

From the Latin word mistūra

Explanation

Mist is a very dense water vapor, almost as thick as fog. Light rain can sometimes form a mist that makes it hard to see the road when you're driving. The mist you see in the air on a damp spring morning is similar to the mist you spray when you water your plants — it's made up of tiny water droplets. As a verb, mist means "to cover with mist," so you might mist your dry plants or watch your windows mist up in the rain. Mist can also refer to a general dimness or cloudiness: "She watched through the mist of her tears."
