Forms

extrāneus (feminine extrānea, neuter extrāneum); first/second-declension adjective[1]

Etymology

It is from extrā “outside” with the suffix -āneus, as Priscian notes.[2][1][3]

Earliest recorded meaning

The OLD's earliest citation is from the Rhetorica ad Herennium, of what is external.[2] Köbler dates it 86/82 BC.[4]

Semantic evolution

It meant external, not inherent, as in the Rhetorica ad Herennium and Cicero, and coming from abroad, foreign.[2][5] Lewis and Short call it mostly post-Augustan.[6] In law it meant not of one's family or household, and as a noun a stranger, and extrāneus hērēs was an heir not under the testator's power.[2] Columella uses it of matters outside the house.[2] Döderlein explains that exterus and externus are foreigners living abroad, peregrīnus and advena those staying for a time.[7]

In Ecclesiastical Latin it meant external, strange, foreign, and as a noun a stranger.[8] Medieval Latin also used it of someone banished.[9] It passed through Old French estrange into English strange, and survives in Italian strano and Romanian străin; English extraneous is a learned borrowing of the 1630s.[10][1]
