Pronunciation

  • /ˈdentɾo/, [ˈd̪ẽn̪.t̪ɾo][1]

Etymology

It is inherited from Late Latin deintro (“from within”), formed of Latin dē (“from”) and intrō (“inside, within”).[2][3][4][1][5] Corominas and Gómez de Silva describe it instead as a Spanish formation from entro (“inside”) with de, like delante, debajo and detrás.[6][7] Since the same combination is found in other Romance languages, Corominas allows that it may already be Vulgar Latin.[6][8][7] Du Cange records Medieval Latin deintro (“inside”) in the Pactus Legis Salicae, where another text has intra.[9]

The same word is Portuguese dentro, Galician dentro, Asturian dientro, Aragonese dintro, Catalan dintre, Occitan dintre and Italian dentro.[3][4][6] Judeo-Spanish has Ladino dientro.[4]

The Latin adverb is formed from in (“in”) with a contrastive suffix.[10] Wiktionary traces it through an older *interus to Proto-Indo-European *h₁énteros (“inner”).[10][1][7]

Earliest recorded meaning

Corominas gives a charter of 1074 as the first record.[8][6] In the Cantar de mio Cid (c. 1140, known from a 14th-century copy) the people of a town shut their gates and „los de dentro non les querién tornar palabra”, “those inside would not answer them”.[11] The Cid also uses it before a preposition: dentro en Burgos, dentro a Valencia, dentro de los corazones.[12]

Semantic evolution

Berceo used dentro but more often the older entro, and in the Libro de Alexandre dentro could still mean “from inside”.[6] Medieval texts preferred dentro en as a preposition (the Cid, Berceo, the Cancionero de Baena), and this was still used by Lope.[6] Dentro directly before a noun (dentro la casa) is found only in some Golden Age prose and above all in verse.[6][13] Cuervo noted that the adverbial use had come to prevail over the prepositional one.[14]

The Diccionario de Autoridades already recorded the sense of time, “within a set period” (dentro del año).[15] In 1884 the Academy noted that the word combines with de, por and hacia.[16] In Chile popular speech made a noun of it, dentro “income”, and in Cuba la de dentro is a card in the game of monte.[17][18]

Timeline

  • 1074 – first record, in a charter.[8][6]
  • c. 1140 – the Cantar de mio Cid has dentro and the derivative adentro.[11][8]
  • 1250–1279 – Alfonso X's Lapidario uses dentro en “within” of the signs of the zodiac.[19]
  • 1513 – Nebrija's Vocabulario glosses the adverb as Latin intus.[20]
  • 1527 – the first record from the Americas, in Santa Marta: dentro en su cámara.[21]
  • 1611 – Covarrubias calls it an adverb of place (intus) and, before a noun, a preposition (intra).[22]
  • 1884 – the Academy's dictionary gives the etymology from de and Latin intro.[16]
