Having deliberately lied under oath in a court of law; guilty of perjury.
From Old French 'parjurer,' combining 'par-' (by) and 'jurer' (to swear). The root emphasizes breaking a sacred oath.
Perjury is so serious that in many countries it can land you in prison longer than the original crime you were testifying about—society takes oath-breaking extremely seriously.
