Forms

noventa m or f[1] Old Galician-Portuguese wrote nouéénta, nouaenta and noueeta;[2][3] noventa is recorded from the 15th century.[2][3]

Etymology

It is inherited from Vulgar Latin *nōvāgintā, written Old Galician-Portuguese noveenta and Old Galician-Portuguese novaenta in the oldest texts.[3][4][1] The Vulgar Latin form is an alteration of classical Latin nōnāgintā (“ninety”) under the influence of novem (“nine”).[1][4][5] Nascentes adds that the next lower ten, oitenta, in which the vowel of the first syllable is clearly heard, helped to shape the new form.[6]

The same Latin word is Galician noventa, Spanish noventa, Catalan novanta, Italian novanta and French nonante;[7][1][8] Old Spanish also had novaenta, and Catalan noranta owes its -r- to coranta (“forty”).[7][1][8]

The Latin numeral goes back to an earlier *nūnāgintā, Proto-Italic *nounāgəmtā, from Proto-Indo-European *h₁néwn̥dḱomt (“nine tens”); its Greek cognate is Ancient Greek ἐνενήκοντα (enenḗkonta).[1]

Earliest recorded meaning

Cunha dates nouéénta and nouaenta to the 13th century.[2] The 14th-century Crónica Troiana counts the years from the creation of the world to the birth of Christ as cinquo mill et çento et noueenta et noue años “five thousand one hundred and ninety-nine years”.[9] Houaiss's first dated record is from 1365, spelt noveenta.[3]

Semantic evolution

The word has always been the cardinal number “ninety”.[3][2] Bluteau (1712–1728) gives it with Latin equivalents and with phrases such as noventa vezes “ninety times” and velho de noventa annos “a man of ninety”.[10] Modern dictionaries add the use as a noun for the figure 90 and for the ninetieth item of a series.[3][11][12] The informal noventão “a man in his nineties” is formed from it.[13]
