+ ==Forms==
+ '''periūrium''' ''n'' (genitive periūriī or periūrī); second declension^(Wiktionary)
+ The OLD lists it under ''pēiūrium'', also spelled ''pēiiūrium'' and ''periūrium''.^(OLD 2012)
+
+ ==Etymology==
+ The OLD forms it from [[pēierō|t=to swear falsely]] with the suffix [[m|la|-ium]];^(OLD 2012) Lewis and Short and Köbler from [[periūrus|t=perjured]].^(Lewis & Short 1879)^(Köbler 2010) Both belong to [[iūrō|t=to swear]], from [[iūs|t=law, oath]].^(de Vaan 2008) According to Leumann, cited by de Vaan, the variation between ⟨-ierāre⟩ and ⟨-iūrāre⟩ comes from a blend of ⟨periūrāre⟩ with ⟨pēierāre⟩ “to make worse”, from [[pēius|t=worse]].^(de Vaan 2008) De Vaan derives the noun ⟨iūs⟩ from [[itc-pro|*jowos|t=oath, law]], from an s-stem of [[ine-pro|*h₂oi-u|t=vital force, eternity]].^(de Vaan 2008)
+
+ ==Earliest recorded meaning==
+ De Vaan dates it from Plautus,^(de Vaan 2008) who speaks of cheats who have made their fortune by usury or by false oaths.^(OLD 2012)
+
+ ==Semantic evolution==
+ It is a breach of oath or a false oath, perjury: Plautus has a man “full of perjury” and people who try to win a lawsuit by perjury.^(OLD 2012) Cicero defines it: not to do what you swore on your conscience to do is perjury.^(Lewis & Short 1879) Köbler gives Cicero as its first author.^(Köbler 2010) Lewis and Short also give the wider sense of perfidy or treachery.^(Wiktionary)^(Lewis & Short 1879)
+
+ Church Latin glosses it “false oath, perjury”.^(Stelten 1995) English ''perjury'' came from it in the late 14th century, through Anglo-French, as a legal term for swearing to what one knows to be false.^(Etymonline)
+
