Etymology

Origin of aver

1350–1400; Middle English < Middle French averer < Medieval Latin advērāre, equivalent to ad- ad- + -vēr- (< Latin vērus true) + -ā- thematic vowel + -re infinitive suffix

Explanation

To aver is to state something or declare something is true. This verb has a serious tone, so you might aver something on a witness stand or you might aver that you won't back down to a challenge. The verb aver comes to English via the Latin root words ad, meaning "to," and verus, meaning "true." The word can have the sense of formally declaring something is true, but it can also mean to report positively: "The grandmother averred that her granddaughter would make a fine veterinarian because of her love and caring for animals."
