Forms

trueno m (plural truenos)[1]

Etymology

It is inherited from Late Latin tronus (“thunder”), a noun formed from the verb *tronare, the source of tronar.[2][3][4] The Academy, García de Diego and Gómez de Silva derive it from the Spanish verb itself.[5][6][7] Corominas notes that the Latin noun is already found in the Tironian notes of the early Middle Ages.[2]

The verb is tonāre (“to thunder”) with an added ⟨r⟩.[2] Corominas explains it from tonitrus (“thunder”), which became *tronitus by metathesis (the source of Old Spanish tronido); the ⟨r⟩ spread from there to the verb and held because ⟨tr-⟩ sounds more like thunder.[2] He rejects Diez's idea of a purely imitative ⟨r⟩ and Schuchardt's of a crossing with tremere (“to tremble”).[2] The DHLE calls the etymology doubtful and also considers tonus (“tone; thunderclap”), which could mean the sound of thunder, with its meaning and form influenced by the verb and by the other Latin noun for thunder.[8] Wiktionary likewise starts from the noun for “tone”, through a Vulgar Latin form with ⟨r⟩.[1]

The same formation is Catalan tro, already in Llull, Galician trono, Portuguese trom, Occitan tron, Italian trono (“thunder (old)”) and Sicilian tronu.[2][1] Old Spanish usually used the noun in ⟨-ido⟩ named above, and the oldest form, in the Libro de Alexandre, is tonidro.[2]

Earliest recorded meaning

The DHLE's first record is the Fazienda de Ultra Mar of Almerich (c. 1200, in a 13th-century copy), where God sends down on the cities of the plain fuego del cielo e truenos e relanpagos “fire from heaven and thunder and lightning”.[8][9] The sense is the noise of thunder.[8] Corominas had dated the word only to the 14th century, already with the sense of the report of a gun.[10]

Semantic evolution

Biblical translations of the 13th century used trueno for the voice of God and for the seven thunders of the Apocalypse, often in the form tueno.[8] From the Poema de Alfonso Onceno (before 1348) the word also named a gun or small piece of artillery, and then its shot; the sense “report of a firearm” is recorded from 1554, in López de Gómara.[8][2] From trueno in that sense came tronera, a gunport.[2][10]

The Academy recorded in 1803 an old piece of artillery called trueno, and in 1970 a hair net worn by the majos of 18th-century Madrid, a sense first found in Ramón de la Cruz in 1769.[8] From the 1840s the word also described a wild, rowdy young man, and a noisy party; in Andalusia trueno gordo is a catastrophe or sensational news.[8] In Colombia and Venezuela it is a firecracker.[8] In Panama and Ecuador it is slang for a pistol.[11]
