mist: [OE] Mist is a member of quite a widespread Indo-European family of ‘mist’-words. Dutch and Swedish share mist, and among the non- Germanic languages Greek has omíkhlē, Lithuanian and Latvia migla, Serbo-Croat màgla, Polish mgła, and Russian mgla, all meaning ‘mist’, besides Sanskrit mēghas ‘cloud’, which all point back to an Indo- European ancestor *migh-, *meigh-.

mist (n.)youdaoicibaDictYouDict
Old English mist "dimness (of eyesight), mist" (earliest in compounds, such as misthleoðu "misty cliffs," wælmist "mist of death"), from Proto-Germanic *mikhstaz (cognates: Middle Low German mist, Dutch mist, Icelandic mistur, Norwegian and Swedish mist), perhaps from PIE *meigh- "to urinate" (cognates: Greek omikhle, Old Church Slavonic migla, Sanskrit mih, megha "cloud, mist;" see micturition).
Sometimes distinguished from fog, either as being less opaque or as consisting of drops large enough to have a perceptible downward motion. [OED]
Also in Old English in sense of "dimness of the eyes, either by illness or tears," and in figurative sense of "things that obscure mental vision."
