wiss

• wis

Perhaps an alteration of wis, taken from the incorrect division of iwis (“surely, certainly”) as "I wis", and mistaken for a verb; see wis. Perhaps from (certainly akin to) Old English witan (“to know”); see wit.

wiss (third-person singular simple present wisses, present participle wissing, simple past and past participle wissed)

1. (archaic) To know; to understand.
