Pronunciation

Forms

rato m (plural ratos)[1]

Etymology

It is probably inherited from Latin raptus (“a snatching, abduction”), through the senses “jerk, sudden pull” and, figuratively, “instant”.[2][3][4][1][5] The etymology goes back to Covarrubias and was accepted by Diez, Meyer-Lübke and the Academy;[6][1] Corominas finds no other convincing one, and rejects Spitzer's idea that it comes from the Latin phrase prō ratā parte (“in proportion”).[2] The Latin noun is formed on rapiō (“to seize, snatch”).[6][1] García de Diego explains the sense from the idea of time snatched or lost, and Bénaben from the speed that seizing implies.[7][8]

The noun is also found in Portuguese rato, where in the archaic dialects of Trás-os-Montes it means “moment”.[2][7] Italian ratto keeps the Latin sense “abduction, robbery”, and rapto is the learned Spanish doublet, recorded from the end of the 16th century.[9]

Earliest recorded meaning

Corominas's first record is Berceo.[2][3] In the Milagros (364c), when a Jew throws his son into the furnace, the mother screams and ovo muchas de yentes en un rato venidas “many people came in an instant”;[10] Corominas argues that the urgency of the scene requires the sense “instant”.[2] Berceo's Santo Domingo (c. 1236) has the diminutive ratiello, and the Libro de Apolonio (c. 1240, in a copy of the mid-14th century) has En poco de rato fue conçeio plegado “in a short while the council had gathered”.[11]

Semantic evolution

Corominas holds that the first sense was “instant, a moment's duration”, still general in South America, and that Spain later moved, by a kind of euphemism, to “a fairly long while”, which may have begun before 1495.[2][3] Juan Ruiz writes quando tu non cuydares en un rato lo avrás “when you least expect it you will have it in a moment”, and the sense “moment” survives in Golden Age writers such as Balbuena and Garcilaso and in a proverb collected by Correas.[2] The Spanish sense is announced by Nebrija's adverbial rato ha, rendering Latin dudum “a while ago”, and in 1588 Jerónimo de Mondragón titled a translation of Guicciardini Ratos de recreación.[2][10] Covarrubias defined the word as “a short space of time”, Autoridades as “an indeterminate space of time”, and the Academy's editions of 1817–1884 as “a short space of time”, a definition Corominas calls false for Spain.[2][12]

With bueno or malo the word has meant a passing pleasure or displeasure since Autoridades.[12][4] In the Americas al rato means “immediately” or “soon”, a cada rato “every moment”, and hasta cada rato is a farewell in Argentina, Peru, Colombia, Venezuela and Puerto Rico.[2][13] Más rato is “later” in Peru, Bolivia, Ecuador and Chile, and qué rato “a long time ago” in Guatemala, Nicaragua and Chile.[13]

Timeline

  • 1220–1250 – Berceo's Milagros: en un rato “in an instant”.[2][3]
  • c. 1236 – the diminutive ratiello in Berceo's Santo Domingo.[11]
  • c. 1240 – en poco de rato in the Libro de Apolonio.[11]
  • 1277 – Alfonso X's prose: dun rato a otro “from one moment to another”.[14]
  • c. 1495 – Nebrija renders rato ha by Latin dudum, iamdudum.[10][2]
  • 1588 – Mondragón's translation of Guicciardini is titled Ratos de recreación.[2]
  • 1611 – Covarrubias defines it as a short space of time and derives it from Latin raptus.[2][12]
  • 1726–1739 – Autoridades: “an indeterminate space of time”, and buen rato, mal rato.[12]
  • 1817 – the Academy defines it as “a short space of time”.[15][2]

Meanings

Noun

  1. A while: a period of time, especially a short one: Me quedé un rato en el parque.[4][1]
  2. With buen or mal: a passing pleasure or displeasure: pasar un buen rato, dar un mal rato.[4][16]
  3. (Latin America) A moment, in phrases such as al rato “soon, shortly after” and a cada rato “all the time”.[2][13]

Word family

  • ratito

Usage notes

Phrases include a ratos “now and then”, a ratos perdidos “in one's spare time” and pasar el rato “to pass the time”.[16][1] Corominas stresses that in Spain the word means a fairly long while, so that the American al rato “in a moment” sounds odd to a Spaniard.[2]

The adjective rato “ratified”, from Latin ratus (“confirmed”), the participle of reor (“to think, reckon”), is now used only in matrimonio rato, a marriage solemnly celebrated but not yet consummated.[17][16][1] Colonial deeds use it in the formula firme, rato e grato “firm, ratified and accepted”.[18] The noun rato “male rat”, also “mouse”, comes from rata; it was used in older Spanish, as in an Alfonsine text of 1250–1300 that recommends the flesh of ratos pequennos “small mice”, and Autoridades notes that it survived in some places.[19][20][14][12]
