Pronunciation

  • /teˈsoɾo/, [t̪eˈso.ɾo][1]

Forms

tesoro m (plural tesoros)[1] Old Spanish also wrote thesoro, and had the forms tresoro and trasoro.[2][3] The Diccionario de Autoridades still entered the word under the spelling thesoro.[4]

Etymology

It is inherited from Latin thēsaurus (“treasure; storehouse”), from Ancient Greek θησαυρός (thēsaurós, “storehouse, treasure”).[5][6][7][1] Meyer-Lübke considered it a semi-learned word;[3] Corominas allows this, but finds the development popular in every Romance language, and notes that Old Spanish always wrote it with the voiced ⟨-s-⟩.[5][3]

It is Portuguese tesouro, Galician tesouro, Catalan tresor, Old French tresor and Italian tesoro.[3][1] The ⟨r⟩ of the first syllable in Catalan, French and Old Spanish tresoro anticipates the later ⟨r⟩ of the word, according to Niedermann.[3] Old High German borrowed it as treso.[3]

The Greek word has no etymology;[8] Beekes takes it for a technical loanword, surely from Pre-Greek.[8] Wiktionary mentions an alternative derivation from Ancient Greek τίθημι (títhēmi, “to put, place”).[1]

Earliest recorded meaning

The first CDH hit is in La fazienda de Ultra Mar (c. 1200, in a 13th-century copy): el oro e la plata y el arambre e el fiero foy alçado poral tesoro de la casa del Criador, “the gold and the silver, the copper and the iron were set aside for the treasury of the house of the Creator”.[9] The Fuero de Zorita (1218–c. 1250) translates its Latin heading De eo qui thesaurum veterem invenerit as Del que tesoro uieio fallare, “of him who finds an old treasure”.[9] Corominas has Berceo, in whom the word is frequent, as the first record.[5][6]

Semantic evolution

Alfonso X's Lapidario uses the plural for the chests and strongrooms in which precious stones were kept.[10] Covarrubias in 1611 defined a treasure as a hidden store of money, gold, pearls or jewels so old that nobody remembers its owner, which therefore belongs to the finder; he also gave the word for the dignitary of a church who keeps its treasure.[11][12] The Diccionario de Autoridades added the royal or private treasury and any store of wealth.[13] By 1884 the Academy also had the figurative sense, a person or thing of great value.[14]

In the Americas the word is recorded from 1538 in Lima, often of treasure found in graves; a Guatemalan text of 1635 says such graves were called guacas.[15] The DLE also uses tesoro for the title some authors gave to dictionaries, catalogues and anthologies.[7] In Asturian it means a money box.[5]
