FalsicrimenFal"si*cri"men\ [L.] (Civ. Law) The crime of falsifying. Note: This term in the Roman law included not only forgery, but every species of fraud and deceit. It never has been used in so extensive a sense in modern common law, in which its predominant significance is forgery, though it also includes perjury and offenses of a like character. --Burrill. Greenleaf.
