Pronunciation

  • /esˈtra.ne.o/[1]

Forms

estraneo (feminine estranea, masculine plural estranei, feminine plural estranee)[1] Old forms include Old Italian estranio, Old Italian estrano, Old Italian istraneo and Old Italian stranio.[2][3][4] Estranio remained in poetry.[5][6]

Etymology

It is learned: it is borrowed from Latin extrāneus (“external, foreign, strange”).[7][8][9][10][1] The Latin adjective is formed from extrā (“outside”) with the suffix -āneus,[11][1] and it was the opposite of intrāneus.[12] The adverb itself is contracted from the ablative of exter (“outer”).[1]

The same Latin word, inherited through popular speech, gave Italian strano, so the learned and the inherited word are doublets.[1][4][10] The inherited outcomes elsewhere are French étrange, Catalan estrany, Spanish extraño and Portuguese estranho.[13][14][10]

Earliest recorded meaning

The TLIO's first record is a Pisan translation of Albertano's treatises (1287–1288), where the word describes someone from another country or of another origin than the speaker.[2] DELI dates the sense “having no connection with the people or things in question” to Z. Bencivenni (before 1313), and the noun “a stranger” to the 14th-century Bible translation.[7]

Semantic evolution

Old Italian used the word for what belongs to another country, another circle or institution, or another family, and for what differs in form or nature.[2] The older senses “foreign” and “strange, unusual” lived on in literature, mostly in the forms estranio and estrano: Ariosto's il cavalliero estrano, Tasso's estranio lido “a foreign shore”.[15][6][3]

Tommaseo noted that one can be a foreigner (straniero) without being estraneo to Italy, that is, unconnected with it.[16] In modern use the word means “unconnected, unrelated”, “unfamiliar”, and, as a noun, a person outside a family or group; in medicine corpo estraneo is a foreign body.[9][5][17] Derivatives are recent: estraneità (1850) and estraniarsi (before 1930, transitive estraniare 1918, in Gramsci).[7][8]
