Pronunciation

  • IPA (Ecclesiastical): [kʷa.draˈd͡ʒin.ta][1]

Forms

quadrāgintā (indeclinable)[1]

Etymology

It continues Proto-Indo-European *kʷt(u)r-dḱmt- (“forty”), from Proto-Indo-European *kʷétuores (“four”), the source of quattuor.[2][1] De Vaan reports Schrijver's view that quadr- arose by voicing of /t/ in clusters, as in this numeral, and that the long ā is phonetic, from *kʷadr-Hkmt- as Kortlandt proposed.[2] Cognate with Ancient Greek τετρώκοντα (tetrṓkonta) and Sanskrit चत्वारिंशत् (catvāriṃśát).[1]

Earliest recorded meaning

De Vaan dates it from Plautus onwards, and Plautus has forty-four minae in the Mostellaria.[2][3] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It is the indeclinable numeral forty, as Cicero's man forty years old and Livy's forty-five.[3][5] Medieval writers used it of the forty days of Lent.[6]

Its descendants include French quarante and French quarantaine.[4] Through Italian quaranta giorni “forty days” it gave English quarantine in the 1660s, the period a ship was kept isolated.[7]
