Etymology

Origin of affirmation

First recorded in 1535–45; from Latin affirmātiōn-, stem of affirmātiō, equivalent to affirmāt(us) (past participle of affirmāre affirm ) + -iō -ion

Explanation

An affirmation is a big fat YES, an assertion that something is true. Affirmations can show up in court, or taped to the walls of people who need reassurance. In court, it's a judgment from a higher court that agrees with one from a lower one, or something a religious person who doesn't want to take an oath can use. Quakers use affirmations on the stand instead of swearing, because they always speak plainly. It means to assure, or agree, so you might find affirmations like "You're awesome!" or "Lookin' good" taped to the mirror of people who need to chin up.
