+ ==Etymology==
+ It is from [[m|la|in-|t=not]] and [[ratus]] “fixed, valid”, the participle of [[reor]] “to reckon”.^(OLD 2012)^(Wiktionary)^(Köbler 2010) De Vaan traces ⟨reor⟩ to [[ine-pro|*Hreh₁-]], with ⟨ratus⟩ originally “counted”, hence “legal”, cognate with [[got|𐍂𐌰𐌸𐌾𐍉|tr=raþjo|t=number, account]].^(de Vaan 2008)

+ In law it meant not ratified, invalid, null and void, as in Cicero's ''aliquid inritum facere'' “to annul something”; of hopes or promises unfulfilled, empty, as in Catullus; of efforts ineffectual, vain, so ''in irritum'' “to no effect”, as in Livy; and of a person baffled, disappointed, as in Tibullus.^(OLD 2012)^(Gaffiot 2016)
+
+ In Ecclesiastical Latin it means void, invalid, vain.^(Stelten 1995) ''in irritum dēdūcere'' was to declare void.^(Köbler 2010) Italian ''irrito'' is a learned borrowing.^(Wiktionary)
