Pronunciation

  • Classical: [kʷa.draːˈɡeː.sɪ.mʊs][1]
  • Ecclesiastical: [kʷa.draˈd͡ʒɛː.s̬i.mus][1]

Forms

quadrāgēsimus (feminine quadrāgēsima, neuter quadrāgēsimum); first/second-declension numeral[1] The spelling with ⟨-gēns-⟩ also occurs,[2] and coins of Galba have ⟨QVADRAGENSVMA⟩.[2][3]

Etymology

It is from Latin quadrāgintā (“forty”) + -ēsimus (“-th”).[2][1] De Vaan lists it among the derivatives of quattuor (“four”).[4] Wiktionary traces the numeral ⟨quadrāgintā⟩ to Proto-Indo-European *kʷétwr̥dḱomt (“four tens”).[1] Cognate with Ancient Greek τετρώκοντα (tetrṓkonta) and Sanskrit चत्वारिंशत् (catvāriṃśát).[1]

Earliest recorded meaning

De Vaan and Köbler date it from Cato,[4][5] whose treatise on farming has pars quadrāgēsima, a fortieth part.[3][6]

Semantic evolution

As an ordinal it numbered days, years and fractions, as in Varro, Cicero, Columella and Pliny the Elder.[3] The feminine quadrāgēsima (understood pars) was a fortieth part,[3][7] as of the sum at issue in a lawsuit in Suetonius,[2][3] and especially a tax of one fortieth, 2½ per cent: Tacitus mentions the abolition of the fortieth and fiftieth, Suetonius a man who collected the fortieth in Asia, and inscriptions a procurator of the fortieth of the Gauls.[2][3] Symmachus calls it a customs duty.[3][7]

In Christian Latin, from Jerome on, quadrāgēsima was the forty days' fast, Lent.[3][7][5] Medieval Latin used it for any period of forty days and had mediante quadrāgēsimā for mid-Lent;[8] in England it was also a tax of a fortieth of rents or movable goods.[9] The word for Lent continues in Italian quaresima, French carême, Spanish cuaresma, Portuguese quaresma and Romanian păresimi, and was borrowed into Old Irish, Welsh, Basque and Albanian.[1][6]
