Where this word comes from
From an incorrect division, mistaking iwis (“certain”) for I wis (“I know”). See ywis for more information. The German verb wissen may appear similar, but in fact corresponds etymologically to the English verb wit; both of those verbs ultimately descend from the same Proto-Indo-European root as this one.
