Forms

interno (feminine interna, masculine plural interni, feminine plural interne)[1] Old Italian forms include interna, interne and interane.[2]

Etymology

It is a learned word, borrowed from Latin internus (“inner, internal”), formed on inter (“between, among”).[3][4][5][1] DELI explains the Latin word as built on an unattested *interus, just as infernus (“lower”) is built on inferus.[3][6] The same Latin word gave French interne (14th century) and Spanish interno.[4][7]

According to DELI, all the Italian derivatives were formed later within Romance, at first mostly in medical terms.[3]

Earliest recorded meaning

The TLIO's first record is Francesco da Barberino's Reggimento e costumi di donna (1318–1320), with the sense “lying on the inside”;[2][3][8] DELI's first date is Dante, before 1321, who has the interna riva, the inner shore, of the heavens.[2][3][8]

Semantic evolution

Old Italian already used the adjective figuratively for what concerns the soul and the mind, and for what is hidden or secret.[2] The sense “taking place within a state or a community” is recorded from Guidiccioni, before 1541.[3] As a noun, interno meant the inner self from Annibal Caro, before 1566, and the inside of something from Frugoni (1666); the plural for a state's home affairs dates from 1797 in Venice.[3]

From the 19th century the adjective and the noun named people who live or work within an institution: the boarder at a school (alunno interno, 1869), and a medical student or young doctor working in a hospital (1957).[3] In football interno was an inside forward (1953), and in film interni are scenes shot in a studio (1942).[3] In addresses interno is the number of a flat in a building, and on the telephone an extension.[9][10][1]
