Forms
forteresse f (plural forteresses)[1] Old French forterece, forteresce and fortelece; the spelling forteresse dates from the 14th century.[2][3][4][5] Anglo-Norman also had fortelesce and fortresse.[6]
Etymology
It is formed from French fort + -eresse, from the adjective in the sense “fortified”.[7][8][1][9] Medieval Latin had fortalicia, fortaricia and other variants from 1119.[7] Bloch and Wartburg allow that it may go back to a form Vulgar Latin *fortaricia, beside Old Occitan fortareza and fortaleza;[10] the Grand Robert and the GLLF derive it from that Vulgar Latin form, built on Latin fortis (“strong”).[5][2] Littré explains the forms in ⟨l⟩ and ⟨r⟩ as two forms of the suffix.[3]
Cognate with Catalan fortalesa, Spanish fortaleza and Italian fortezza.[3][4]
Earliest recorded meaning
It is first found in the Roman d'Enéas (about 1160) for a fortified place.[7] The Grand Robert and the GLLF date that text to about 1130.[5][2]
Semantic evolution
From the fortified place, which could defend a town or a whole region, the word passed to a place of safety or a refuge (Calvin, 1541) and to anything that resists from outside.[7][8][11] The romantic period used it for a castle serving as a prison (Mme de Staël, 1810).[7][8] Forteresse volante (about 1943) translates the English flying fortress, the name of an American heavy bomber.[7][8][11]
In the 13th century the noun fort arose beside it in the same sense.[8] English borrowed the Old French word as fortress in the early 14th century.[12]
