Pronunciation

  • /aˈtɾas/, [aˈt̪ɾas][1]

Etymology

It is formed from Spanish a- + tras (“behind”), the second part continuing Latin trāns (“across, beyond”).[2][3][4][5] The REW and García de Diego set up a Latin phrase *ad trans, which Wiktionary follows, and which would also explain Portuguese atrás and Galician atrás.[6][7][1][8] In Spanish the preposition passed from “beyond” to “behind”.[2][9]

The Latin preposition goes back to *trānts and Proto-Indo-European *tr̥h₂-n̥ts (“crossing”), a participle;[10][1] English through comes from the same root.[10][1] In the 1880s Echegaray and Barcia derived the word from Latin retrō (“backwards”).[11][12]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) has the count riding off and looking back, afraid that the Cid would change his mind: tornando va la cabeça e catándos' atrás “he keeps turning his head and looking back”.[13][14] Corominas dates the word to about 1200, in the Vida de Santa María Egipcíaca, and Berceo.[2][3]

Semantic evolution

Old Spanish used it for movement and position to the rear, as in Berceo's tornar la cabeça atrás “to turn one's head back”.[14][13] In Nebrija's Latin–Spanish dictionary of 1492 it renders Latin retro.[15] The Academy's 1817 dictionary gives a sense of time, “in the past”, and the colloquial hacia atrás “the wrong way round”; its 1899 edition adds the interjection ¡atrás!.[16][17]

In the Canaries atrás de is used for detrás de “behind”, perhaps under Portuguese influence.[18][19] In the Spanish of the United States para atrás copies English back (te llamo para atrás “I'll call you back”), and New Mexican Spanish has dar pa atrás “to give back”.[20][21] In Mexico hasta atrás means “very drunk”.[22] Tagalog borrowed the word as atras.[1]
