Pronunciation

  • /ˈtɾeinta/, [ˈt̪ɾẽĩn̪.t̪a][1]

Etymology

It is inherited from Old Spanish treinta, inherited from Latin trīgintā (“thirty”).[2][3][4][1] Corominas assumes that the Latin form was replaced by a Vulgar Latin variant with a changed vowel, perhaps under the influence of trēs, as in the other Romance languages, and that the stressed /i/ of the old pronunciation /treˈinta/ is due to veinte;[2][3] Asturian still keeps it.[2][3] Nascentes explains the Portuguese form in a similar way.[5]

The same Latin word is Portuguese trinta, Galician trinta, Catalan trenta, Aragonese trenta, Occitan trenta, French trente and Italian trenta.[6][7]

The Latin numeral is formed from the word for “three” and the element -gintā (“tens”),[8][9] and goes back to Proto-Indo-European *tridḱómt (“thirty”), cognate with Ancient Greek τριάκοντα (triákonta) and Sanskrit त्रिंशत् (triṃśát).[1]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) has dámosvos en don a vós treinta marcos “we give you thirty marks as a gift”.[10][2] The earliest hit with no later copy is a charter dated in the era of 1335 with the form trinta.[10]

Semantic evolution

The Diccionario de Autoridades records treinta also as the name of a card game in which players ask for cards until they make thirty points.[11] Salvá added the games treinta y cuarenta and the colloquial ponerse a treinta “to get tipsy”,[12] and the 1884 Academy dictionary gave it also as an ordinal (año treinta, el treinta de enero).[13] In Ecuador treinta y uno is a dish of beef tripe.[14]
