Pronunciation

  • Classical: [triːˈkeː.sɪ.mʊs][1]
  • Ecclesiastical: [triˈt͡ʃɛː.s̬i.mus][1]

Forms

trīcēsimus (feminine trīcēsima, neuter trīcēsimum); first/second-declension numeral[1] Also trīcēnsimus.[2][3] The less frequent trīgēsimus is post-Augustan, found in Martial and Justin;[4][3] the OLD notes trig- in Gaius.[2]

Etymology

It is from Latin trīgintā (“thirty”) + -ēsimus (“-th”),[1] formed, as the OLD notes, in the same way as trīcēnī (“thirty each”).[2] For the parallel vīcēsimus (“twentieth”), spelled ⟨vīkēnsumo-⟩ in an inscription, de Vaan reconstructs Proto-Italic *wīkenssamo-, with the suffix Proto-Indo-European *-tmHo- that Indo-Iranian also has.[5] He lists trīgintā among the derivatives of trēs (“three”) and reconstructs Proto-Indo-European *trih2dḱomth2 (“thirty”).[5]

Earliest recorded meaning

Köbler's first source is Cicero,[6] who writes in a letter idem tricesimo post die feci, “I did the same thirty days later”.[4]

Semantic evolution

It is the ordinal “thirtieth”, used of days and years: Cicero has tertius et tricesimus annus, “the thirty-third year”, Livy tricesimum annum agens, “in his thirtieth year”, and Galba, writing to Cicero, legio quinta tricesima, the thirty-fifth legion.[4][3] Horace has tricesima sabbata.[4][3] Ecclesiastical Latin uses both tricesimus and trigesimus.[7]

In British medieval Latin it is also used of the thirtieth day after a death or the day of the last mass of a trental, and then as a noun.[8] Italian trentesimo continues it.[9]
