Pronunciation

  • Classical: [kʷiːŋ.kʷaːˈɡeː.sɪ.mʊs][1]
  • Ecclesiastical: [kʷiŋ.kʷaˈd͡ʒɛː.s̬i.mus][1]

Forms

quīnquāgēsimus (feminine quīnquāgēsima, neuter quīnquāgēsimum); first/second-declension numeral[1] It is also spelled quinquāgēnsimus.[2]

Etymology

It is from Latin quīnquāgintā (“fifty”) + -ēsimus.[2][1] That numeral goes back to quīnque (“five”); according to de Vaan its ⟨ā⟩, for an expected *quinquēgintā, was taken from the word for forty.[3] He traces the word for five to Proto-Italic *kʷenkʷe and Proto-Indo-European *penkʷe (“five”).[3]

Earliest recorded meaning

Köbler records it first in Plautus.[4] It means “fiftieth”: Cicero dates an event to about the three hundred and fiftieth year after the founding of Rome.[5][6]

Semantic evolution

Pliny the Elder uses it of a man's fifty-first year, and the OLD records a yield of up to fiftyfold, cum quinquagesimo fenore.[5][2] The feminine, with pars understood, is a fiftieth part: Vitruvius uses it in proportions, and in the Verrines Cicero complains of fiftieths exacted on top of the tithe.[2][5] As a tax, the two per cent duty, it appears in Tacitus, who records its abolition, and in Symmachus.[2][6]

In church use the feminine, with diēs understood, became the name of Pentecost, the fiftieth day after Easter.[6][7] Medieval writers in Britain also use Quinquagesima for the period from the Sunday before Lent to Easter, and for that Sunday itself; a letter of 798 in Alcuin's correspondence explains the name.[7]
