Forms

alieno (feminine aliena, masculine plural alieni, feminine plural aliene)[1]

Etymology

It is borrowed from Latin aliēnus (“belonging to others, foreign”), a learned word, from alius (“other”).[2][3][4][5][1] The sense “extraterrestrial” is a recent loan from English alien: the LEI calls it a borrowing and Devoto–Oli a calque, dated 1978.[6][7][5]

The Latin adjective survives as a popular word only in Spanish ajeno, Portuguese alheio, Galician alleo and Sardinian andzénu in Logudorese.[6][8] Learned forms like the Italian one are Old French alien (“foreign”) (11th century), Catalan aliè (1370) and Spanish alieno.[6][9]

The Latin pronoun continues Proto-Italic *aljo- and Proto-Indo-European *h₂el-io- (“another”), the source also of Ancient Greek ἄλλος (állos), Gothic 𐌰𐌻𐌾𐌹𐍃 (aljis) and Old Irish aile.[10][3] The suffix of the Latin adjective is unclear: Avviamento explains it as -īnus dissimilated to -ēnus after the stem vowel, which de Vaan finds unlikely; he cites Nussbaum's proposal of a form built on a locative meaning “elsewhere”.[10][11]

Earliest recorded meaning

DELI's first record is in the Novellino, at the end of the 13th century, with the sense “belonging to someone else”.[2] The TLIO and the LEI give an earlier example from Panuccio del Bagno of Pisa (before 1276), who speaks of an adverse, self-defeating provedensa aliena.[12][6]

Semantic evolution

The sense “contrary, hostile” is recorded in Domenico Cavalca (before 1342),[2] and, from it grew the modern construction alieno da, “averse to, shunning”: Lorenzo de' Medici writes that he had long been assai alieno da simili feste, far from such festivities.[13][6] The older sense “someone else's, foreign” passed into literary use;[4][5] Machiavelli speaks of making war with one's own weapons e non con le aliene.[4][5] In Sicilian, alienu came to mean “absent-minded, indifferent”.[6]

The science-fiction sense, a being from another planet, came from English in the late 20th century;[7][6] GDLI quotes Tullio Kezich in La Repubblica (1984): Chi ha detto che gli alieni sono grandi come uomini? (“Who said aliens are as big as people?”).[14] From it comes the figurative use for a person who feels out of place.[7][15]
