    • iwis Certainly; surely; truly; to wit. This word, very common in Middle English, lost somewhat of its literal force, and became in later use a term of slight emphasis, often meaningless. In the later ballads, and hence archaically in modern use, it is thrown in parenthetically, often as a metrical expletive, and is commonly printed as two words, I wis, taken to mean ‘I think’ or ‘I guess.’ See the etymology.
    • n iwis Certainty: used in the adverbial phrases mid iwisse, or to iwisse, for certain, certainly.

    • adv Iwis i-wis′ certainly—sometimes ignorantly written I wis, as if 'I know.'
