Forms

aliēnum n (genitive aliēnī); second declension[1]

Etymology

It is the neuter of aliēnus (“belonging to another”) used as a noun.[1][2] ⟨Aliēnus⟩ is formed from alius (“other”), which de Vaan traces to Proto-Italic *aljo- (“another”) and Proto-Indo-European *h₂el-yo- (“another”), cognate with Ancient Greek ἄλλος (állos, “other”) and Gothic 𐌰𐌻𐌾𐌹𐍃 (aljis, “other”); he finds the suffix of ⟨aliēnus⟩ unexplained.[3]

Earliest recorded meaning

Its first example in the OLD is Naevius, of what belonged to others: “as much of others' property as I had”.[1][2]

Semantic evolution

It is the property or land of others, and in Tacitus foreign soil.[1] The plural aliēna is other people's affairs, as Terence's “that they see and judge others' affairs better than their own”, and the views of others, as Cicero's Epicurus who said what others had said on physics.[1] Horace uses the plural of foreign matter, and Ovid's aliēna loquī is to rave in delirium.[1]
