Perjure

Part of speech: noun (n.)

A perjured person. [Obs.] Shak.

Part of speech: verb (v.)

1. To cause to violate an oath or a vow; to cause to make oath knowingly to what is untrue; to make guilty of perjury; to forswear; to corrupt; -- often used reflexively; as, he perjured himself. Want will perjure The ne'er-touched vestal. Shak.

2. To make a false oath to; to deceive by oaths and protestations. [Obs.] And with a virgin innocence did pray For me, that perjured her. J. Fletcher.

Synonyms: Perjure, Forswear. These words have been used interchangeably; but there is a tendency to restrict perjure to that species of forswearing which constitutes the crime of perjury at law, namely, the willful violation of an oath administered by a magistrate or according to law.
