Forms

interne (plural internes)[1]

Etymology

It is borrowed from Latin internus (“inner, internal”),[2][1][3] together with its neuter plural interna (“the inside, the entrails”).[4] The Latin adjective is formed from inter (“between, within”) with the suffix -nus.[5][6]

Earliest recorded meaning

It first appears as a noun, “what is inside”, in an alchemical treatise attributed to Nicolas Flamel: Mais si pour avoir son interne, L'on en separoit son externe.[5][2] Littré, Bloch and Wartburg and Rey place the text in the 14th century; the TLFi dates it by its first edition, 1561.[5][3][4][2] The adjective is taken up about 1560 by Paré, in maladie interne, a disease of an inner organ.[4][2]

Semantic evolution

From medicine the adjective passed to abstract use, as in Montaigne's qualitez internes of the soul (1580).[4][5] From 1597 it meant situated inside or facing inwards, hence its use in geometry (angles internes, 1704).[4][2] It was used of feelings from the mid-18th century, and of introspection in observation interne (1845).[4]

In the 19th century the noun came to denote a medical student who lives in the hospital where he serves (1818) and a pupil who boards at school (1829), the use that goes with internat.[2][4] Médecine interne dates from about 1973, after English.[4][7] English borrowed intern “assistant doctor” from the French noun in 1879, and the verb intern “confine” from interner in 1866.[8]
