The act or practice of defrauding; the commission of fraud or deception to deprive someone of money or property.
From defraud + -ation (Latin suffix creating nouns). Defraud comes from Old French frauder, from Latin fraudare (to deceive).
Defraudation is the formal legal term for scams and theft-by-deception—it sounds old-fashioned but appears in courtroom documents when prosecuting people who've tricked others out of money.
