Forms

tronido m (plural tronidos)[1] Old Spanish tonidro, the older form, is found in the Libro de Alexandre; elsewhere the texts have tronido from the 13th century on, and atronido occurs in the Poema de Fernán González.[2][3] Asturian has troníu and troñíos, and tronido is still said in Astorga, Santander and other neighbouring areas;[2][4] Andalusian tronío is a variant of the same word.[2][4]

Etymology

It is inherited from Old Spanish tronido, inherited from Latin tonitrus (“thunder”).[5][1][3] The older Old Spanish form tonidro still has the consonants in the Latin order.[2][6]

According to Corominas the Latin word first became *tronitus by metathesis of the /r/, and the stress then moved to the next-to-last syllable, as sonitus became sonido when the participles in -ĭtus were replaced by Spanish forms in -ido such as vendido and perdido.[2][3] From this word the initial tr- spread to the verb tronar, from Latin tonāre (“to thunder”), and the expressive force of tr- helped it to last.[2][6] The same Latin noun, stressed on its first syllable, gave estruendo and Portuguese estrondo.[4][1]

The Latin noun also gave French tonnerre, Old Occitan toneire and Romanian tunet.[7][1] In Latin the noun is probably formed from that verb with a suffix -tus, its -r- added under the influence of fulgetrum (“lightning”).[8][1]

Earliest recorded meaning

The Libro de Alexandre (1240–1250) has the old form tonidro for “thunder”: la voz cuemo tonidro “a voice like thunder”; one of its manuscripts, of the early 15th century, reads tronido there.[2][3][9] In the Estoria de España of Alfonso X a people that frightened the whole world is compared to the great tronido that frightens men.[10][9]

Semantic evolution

The first sense is the thunder that follows lightning, and it is the only one Nebrija gives: tronido o trueno, Latin tonitrus.[3][11] A more general sense, a loud noise or bang, is recorded in the Crónica del halconero (c. 1454); Juan Ruiz de Alarcón used it for the report of a gun.[3][2]

The Academy marked the word as antiquated in 1817 and 1843, and Domínguez in 1847 called it old and mostly poetic.[12][13][3] In 1869 the Academy dropped the label and added the sense “bang”.[14][3] The word lived on in the dialects: in Andalusia it came to mean show, swagger or ostentation, and the DHLE finds it very common in Mexico from the late 20th century.[2][15][3] Its latest dictionary sense is a noisy failure.[5][1]

Timeline
