Forms

solitaire (plural solitaires)[1]

Etymology

It is borrowed from Latin sōlitārius (“isolated, solitary”), from sōlus (“alone”), the source of seul.[2][3][4][5][1][6] Bloch and Wartburg date it to about 1155, the TLFi and the DHLF to the end of the 12th century.[4][2][3]

Old and Middle French also had soltain (about 1160, in the Roman d'Énéas), sostain and soutain (Chrétien de Troyes), inherited from Vulgar Latin *sōlitānus, from Late Latin sōlitāneus (“separated, isolated”).[2][4][1] A form sultif or soutif, of the same origin, took its suffix from a word meaning “clever”, a variant of soutil (see subtil), since a clever act can also be a secret one.[2][4] These words survived until the 15th century.[4]

Cognate with Old Occitan solitari, Spanish solitario and Italian solitario.[7]

Earliest recorded meaning

It is first recorded at the end of the 12th century in the Sermons of Saint Gregory on Ezekiel, of a person who is alone or lives in solitude (simple et solitaire).[2][8]

Semantic evolution

In Old French the adjective already described what happens in isolation (vie solitaire, about 1200), a person who lives alone and likes it, what leads one to seek solitude (humeur solitaire), and a deserted place (lieus solitaires, Rutebeuf, 1285).[2][3] As a noun it named, from about 1200, a hermit or monk living apart, in the 17th century especially the solitaires of Port-Royal (1680, Richelet), and more generally anyone who lives alone.[2][3]

Of things and lower animals it came to mean “not accompanied by others of its kind”: in architecture colonne solitaire (1701, Furetière), then ver solitaire, the common name of the tapeworm (1759); it is used in botany of a single flower on an unbranched stem (1805) and in zoology of an animal living alone (1839).[2][3][8] The noun also named a game played alone (1752), an extinct bird of the Mascarene Islands (1764), a diamond set by itself (1798) and an old boar living apart (1834).[3][2] From solo sailing comes en solitaire.[3]
