quinquennium

== English == === Alternative forms === quinquennie === Etymology === From Latin quīnquennium, from quinquennis (“5-year”) + -ium (suffix forming abstract nouns). === Pronunciation === (General American) IPA(key): /kwɪŋˈkwɛniəm/ (Received Pronunciation) IPA(key): /kwɪŋˈkwɛnɪəm/, /kwɪnˈkwɛnɪəm/ === Noun === quinquennium (plural quinquenniums or quinquennia) A period of five years.

This is not usually intended in English but may occur in translations of classical texts. Pentad or the neologism quintade are sometimes used when one wishes to specify the first and second halves of calendrical decades. Lustrum and luster are particularly used for the 5 year periods of the Roman censuses, after the purification ritual that usually followed the count. ==== Synonyms ==== quinquennial, quinquennal, quinquenniad, quintennium, pentad, quintade, lustrum, luster ==== Hyponyms ==== See Thesaurus:quintet ==== Related terms ==== (adj.): quinquennial, quinquennal, quintennial ==== Translations ==== === References === “quinquennium, n.”, in OED Online ⁠, Oxford: Oxford University Press, 2022. == French == === Etymology === Borrowed from Latin quinquennium. === Pronunciation === IPA(key): /kɛ̃.kɛ.njɔm/ ~ /kɛ̃.ke.njɔm/ === Noun === quinquennium m (plural quinquenniums) quinquennium (a period of five years) Synonym: lustre ==== Usage notes ==== Chiefly used in historiography of ancient Rome.
