Forms
sessenta m or f[1] Old Galician-Portuguese wrote sesaenta, saseenta, sasseenta and seseẽta; the 15th century has sesemta and ssesseenta.[2][3][4]
Etymology
It is inherited from Latin sexāgintā (“sixty”), written Old Galician-Portuguese sesaenta in the oldest texts.[2][3][1][5] Nascentes traces the modern form through the old Old Galician-Portuguese sessaenta and Old Galician-Portuguese sesseenta, and notes that the Latin /ks/ had already become a double /s/ in popular Latin.[5][6] Cunha compares seis.[3]
The same Latin word is Galician sesenta, Spanish sesenta, Catalan seixanta, Occitan seissanta, French soixante, Italian sessanta and Sardinian sessanta.[7][1] Old Spanish had forms close to the Portuguese ones, Old Spanish sesaenta and Old Spanish seseenta.[8]
The Latin numeral is formed from sex (“six”) with the tens suffix -gintā.[9] Wiktionary takes it back to Proto-Indo-European *sweḱsḱomt, from earlier *swéḱs-dḱomt (“six-ten”), with Ancient Greek ἑξήκοντα (hexḗkonta) as a cognate.[1]
Earliest recorded meaning
Lorenzo's chronology finds the numeral in a charter of 1282, sesaenta liuras “sixty pounds”, and in the Cantigas de Santa Maria, where cantiga 349 counts a year ontre mil e sesaenta.[4] The Crónica Geral of 1344 has sasẽeta cavallos “sixty horses”, and the Miragres de Santiago have saseenta caualeiros “sixty knights”.[4]
Semantic evolution
The meaning has not changed: the word is the cardinal number six times ten, used before a noun and on its own as the name of the number.[2][10] The medieval texts often wrote it in Roman numerals, LX or LXa.[11] Barbosa (1611) and Bluteau (1712) give with it the Latin equivalents of sessenta vezes “sixty times” and de sessenta annos “sixty years old”.[12][13] Today it is also used after a noun for the sixtieth item of a series.[2][10]
