Word History

Etymology

Noun

borrowed from Spanish or Italian bomba or French bombe, all probably in part from an onomatopoeic base bomb- (as in Greek bómbos "booming, humming," Old Norse bumba "drum," Lithuanian bambėti "to mutter, mumble," Albanian bumbullin "it is thundering"), in part back-formation from Medieval Latin bombardus or Middle French bombarde bombard entry 1

Note: The origin and transmission of bomba, bombe, etc., in the sense "explosive device, projectile, etc.," among European languages is not certain. Bomba is attested earliest in Spanish, appearing several times in the second half of the 16th century (canto 18 of La Araucana of Alonso de Ercilla y Zúñiga, the Descripción general de África of Luis del Mármol, the Historia de las cosas … del Gran Reyno de la China of Juan González de Mendoza). Mendoza's book (1585) is the source of an early and aberrant instance of bomb in English: his bombas de fuego is rendered as "bomes of fire" in Robert Parke's translation (The Historie of the Great and Mightie Kingdome of China, London, 1588, p. 65). Bomba is recorded as Italian in Antoine Oudin's Italian-French dictionary (Recherches italiennes et françoises, Paris, 1640), where it is glossed "bombe, ou balon de feu" ("bomb, or ball of fire"), though it is not recorded in an Italian text until 1686 (Paolo Segneri, Il cristiano instruito, Florence, p. 327); Oudin's gloss also apparently constitutes the first record in French. Significantly earlier than any of these is Latin bombus, which occurs twice in the Commentarii, an account of the exploits of the condottiere Jacopo Piccinino in 1452-53 by the Neapolitan humanist Giannantonio de' Pandone, "il Porcellio" (ca. 1405-85); Pandone's bombus appears to be some sort of exploding projectile ("Hic Tibertus Dux bombi fulmine in ulna sauciatur" - "Here Tibertus [the condottiere Tiberto Brandolini] was wounded in the forearm by the flash of a bombus"); the 18th-century lexicographer Du Cange, in Glossarium mediae et infimae Latinitatis, glosses bombus in this passage, alluding to French bombe, as pila incendiaria, "fireball." Spanish bomba in the sense "pump," attested from the early 16th century, is probably an independent formation; cf. pump entry 1.
