Usage

What does allegation mean? An allegation is an accusation or claim that something wrong has been done, especially a crime. The word often implies that the thing claimed has not been confirmed or proven or that the claim has been made without proof or before proof is available. Allegation is the noun form of the verb allege, meaning to claim without proof or before proof is available. Related forms include the adjective alleged and the adverb allegedly. The word allegation is most commonly used in a legal context, especially in journalism in reports about a person who has been accused of a crime or other wrongdoing but who has not been convicted. Using the word allegation allows journalists to talk about accusations without seeming to presume guilt (and getting sued for libel). Example: We will prove that the allegations against my client are absolutely baseless.

Etymology

Origin of allegation

1375–1425; late Middle English < Latin allēgātiōn- (stem of allēgātiō ), equivalent to allēgāt ( us ), past participle of allēgāre to adduce in support of a plea ( al- al- + -lēgāre, derivative of lēx law; see legal) + -iōn- -ion

Explanation

An allegation is an accusation, which is sometimes true and sometimes not. If you say your sister stole a candy bar but you don't have any proof that she did it, you have made an allegation. In the legal system, an allegation is a formal claim against someone. It sparks an investigation that leads to someone being proven innocent or found guilty. In everyday use, however, an allegation is what someone thinks, whether or not there is proof. For example, if someone makes an allegation that you're a terrible driver, they might base it on their own experience, but they won't be able to prove it.
