avouch
Swear it's so
Avouch is a formal or archaic verb meaning to affirm, declare, or guarantee as true: I can avouch for his honesty.
It carries more weight than simply saying something—to avouch is to stake your credibility on it.
The word appears mainly in legal contexts and older literature, largely replaced in modern speech by vouch or vouch for.
