Forms
aliēnigenus (feminine aliēnigena, neuter aliēnigenum); first/second-declension adjective[1]
Etymology
It is from Latin aliēnus (“belonging to others”) + -genus (“born”).[2][3] aliēnus is derived from alius (“other”),[4] which goes back to Proto-Italic *al-jo- and Proto-Indo-European *h₂el-io- (“another”).[4]
Earliest recorded meaning
Lucretius uses it first, of things made of matter of a different kind: food would seem to consist of alien things.[2][5]
Semantic evolution
In Valerius Maximus it means “foreign”, of examples, studies, cities and a woman of foreign blood, as opposed to native ones,[2][5] and Seneca speaks of foreign rites.[2][5] Columella uses it of plants grown from seed brought from elsewhere and of chicks hatched from another bird's eggs.[2] An inscription forbids anyone to bring a stranger's body into a tomb.[2][5]
Late writers use it of foreign peoples and lands;[5] Ammianus speaks of joining one's own forces with foreign ones.[5]
