átomo m (plural átomos)[1]
Etymology
It is borrowed from Latin atomus (“indivisible; atom”), a learned word first found in the works of Don Juan Manuel, who died in 1348.[2][3][4][1] The Latin word is taken from Ancient Greek ἄτομος (átomos, “uncut, indivisible”),[2][5][1] formed from ἀ- (a-, “not”) and τομ- (tom-), the o-grade of the root of τέμνω (témnō, “to cut”).[1][6] The Greek philosophers Democritus and Epicurus used it for the indivisible particle of matter, and 19th-century chemistry gave it its modern sense.[7]
The Latin word also had a popular outcome in Italian, Italian attimo (“instant, moment”).[8] Corominas lists diatomea as a learned word from διάτομος (diátomos, “cut in two”), another derivative of the same Greek verb.[2][3]
Earliest recorded meaning
Corominas dates the first record to Don Juan Manuel, about 1330.[2][3] The DEMel lists the word in the vocabulary of his works,[9] and DICCA-XV reports a CORDE record of 1327–1332.[10] The sense was the philosophers' one: the smallest body, thought to be impossible to divide.[2][11]
Semantic evolution
Nebrija glossed it about 1495 as a thing that cannot be divided, with Latin atomus.[10] Covarrubias in 1611 used it for the tiny motes that float in the air and are seen only in a sunbeam coming through a crack in the window, and also for the elements, whose parts are all of one kind.[12] Autoridades kept the indivisible body and the motes, and added a figurative sense, any very small thing, much used by the poets, with phrases such as no exceder en un átomo “not to go beyond something in the least”.[11][13]
Gaspar y Roig in 1853 noted an obsolete sense, the smallest parts of an hour,[14] which goes back to Medieval Latin, where atomus meant the smallest part of an hour.[15] In 1899 the Academy defined the atom as the hypothetical primary element of bodies, infinitely small,[16] and the 2001 edition describes it as the smallest quantity of a chemical element, made of a nucleus with protons and neutrons and orbiting electrons.[4] The first record from the Americas, in 1591 in Mexico City, already uses it for a tiny amount: un áthomo de azogue “an atom of quicksilver”.[17]
