Pronunciation

Forms

jumeau m (plural jumeaux, feminine jumelle)[1] Old French jumel, earlier gemel, gemeau.[2][1][3]

Etymology

It is inherited from Old French jumel, inherited from Latin gemellus (“twin”), a diminutive of geminus (“twin”), which it replaced for its greater expressiveness.[4][5][6] The /ə/ of the first syllable became /y/ under the influence of the two labial consonants around it, and the new form soon replaced gemeau, which survives in the parlers of the east and in the astrological gémeau.[4][5][7]

Cognate with Italian gemello, Spanish gemelo, Portuguese gémeo and Romanian geamăn.[1][8]

Earliest recorded meaning

It is first found about 1165 as a noun for children born at one birth, in Guillaume d'Angleterre, attributed to Chrétien de Troyes.[4][5] The adjective follows at the end of the 12th century in Floire et Blancheflor: sa suer jumele “her twin sister”.[4][9]

Semantic evolution

Jumeau lives in the northern dialects, while the south and the centre of France say besson, from Vulgar Latin *bissus of Gallo-Roman, from bis (“twice”);[5][7][4] besson was common in Old French until the 16th century and is now regional.[5][7][4] By extension the adjective was applied from the late 12th century to things exactly alike.[4][5]

In anatomy the twin muscles of the calf have been jumeaux since 1747, a sense once given to gémeau, and in butchery a cut from the shoulder of beef (1931).[4][5] The feminine jumelle specialized in technical uses and has meant binoculars since 1829.[5][7] Vrais and faux jumeaux are recorded in 1941 in Jean Rostand.[10]
