Pronunciation

Forms

sous-marin m (plural sous-marins)[1] As an adjective: feminine sous-marine, plurals sous-marins, sous-marines.[1] First written soumarin (1555–1557); sous-marin from 1729.[2][3]

Etymology

It is formed from French sous- + marin (“of the sea”).[2][4][5][1] The adjective is from Latin marīnus (“of the sea”), from mare (“sea”).[5][6]

For the noun “submarine” the TLFi compares the English word submarine, recorded in that sense in 1899.[2]

Earliest recorded meaning

Charles Toutain's Agamemnon has soumarin “lying under the waves, at the bottom of the sea”; the TLFi dates the edition 1557, the GLLF and the Grand Robert 1555.[2][3][4] The word was rare before it was taken up again in 1729.[5][4]

Semantic evolution

The adjective became a term of navigation with navigation sous-marine (Académie, 1835) and bateau sous-marin (1858).[2] The Quemada datings find bateau sous-marin as early as 1840, in the Magasin pittoresque.[7]

The noun un sous-marin, a vessel built to sail under water, is dated 1875 by Bloch and Wartburg, 1896 by the TLFi and 1907 by Rey.[5][2][8] Figuratively it is used of a person with secret aims.[8] The derivative sous-marinier “submariner” dates from 1934, and anti-sous-marin from 1918.[8][2]
