Pronunciation

  • /tɾoˈnaɾ/, [t̪ɾoˈnaɾ][1]

Forms

tronar (first-person singular present trueno, first-person singular preterite troné, past participle tronado)[1] Old Spanish also had truenar, which Alfonso de Palencia used in 1490.[2][3]

Etymology

It is inherited from Latin tonāre (“to thunder”), with an /r/ taken from the noun Old Spanish tronido (“thunder”).[3][4][5][1] That noun was first tonidro, from tonitrus (“thunder”), and took its /r/ by metathesis; the old form is found in the Libro de Alexandre.[3][4] Old Spanish tonar without the /r/ is listed by García de Diego, and Menéndez Pidal heard tona (“thunderstorm”) in western Asturias, but Corominas thinks such forms were never widespread.[6][3]

The /r/ is shared by Catalan tronar, Occitan tronar and Portuguese troar, while French tonner, Italian tonare and Romanian tuna keep the Latin form.[7][1] Coromines believes the /r/ was already widespread in Vulgar Latin, where Vulgar Latin *tronitus had arisen by metathesis from the Latin noun, which was popularly stressed on the /i/.[8] The REW offers this explanation beside Schuchardt's, that /tr/ had become a kind of sound-imitating element, as in tremō (“to tremble”).[7]

The Latin verb is from Proto-Italic *tonaō and Proto-Indo-European *(s)tenh₂- (“to thunder”), the root of English thunder.[1] The OLD compares Old English þunor and Old High German donar, both “thunder”.[9]

Earliest recorded meaning

The DHLE's first record is the Semejanza del mundo, which it dates c. 1223 from the manuscript in the Biblioteca Nacional.[2] Among texts copied in their own century, Alfonso X's General Estoria (1272–1275) has the verb in its first sense, of thunder in the sky: començo a tronar & relampagar muy fuert “it began to thunder and lighten very fiercely”.[10][11] Corominas, who had no record before Nebrija at hand, dated it 1490 in the Breve diccionario.[3][4]

Semantic evolution

From the General Estoria on, the verb also had a personal subject, Jupiter or God making the thunder, and by the 15th century it was used of any loud noise like thunder.[2] The Diccionario de Autoridades gave the extension to the noise of firearms, with Espinar's advice that good gunpowder should not thunder much, and the phrase por lo que pudiere tronar “just in case”.[12]

Salvá in 1846 recorded tronar “to die” and “to go bankrupt” (ese tronó), the Academy in 1869 added “to lose all one's money at cards” and tronar con uno “to fall out with someone”, and in 1899 “to be ruined” and “to rail violently against something”.[13][14][15] In Mexico and Central America the verb has meant “to shoot, execute” in Malaret's and Santamaría's dictionaries of the 1940s; it also means “to fail an examination”, “to sack someone” and, in Ecuador, “to die”.[16][17][18]

The derivative tronada “thunderstorm” is, according to Corominas, the source of the English word tornado, recorded from 1556.[4]
