Pronunciation
Forms
forêt f (plural forêts)[1] Old French forest; the spelling forêt dates from the 17th century.[2][3]
Etymology
It is inherited from Old French forest, inherited from Late Latin forestis, probably from the phrase “silva forestis”, a forest under the king's court of justice,[4][2][5][6][3][7] from Latin forum (“court of justice”);[4][2][5] the Late Latin word named, from 648, land whose use the king reserved for himself.[4][2] The legal sense found in the earliest texts makes a Frankish *forhist (“fir wood”) unlikely.[4][2][5] Guiraud and others relate “forestis” instead to forīs (“outside”), a wood outside the commune's bounds.[6][2][8]
Italian foresta and German Forst were borrowed from French.[5]
Earliest recorded meaning
Philippe de Thaon's Bestiaire (1121–1134) uses forest for a wide stretch of land covered with trees;[4] the legal sense of a royal forest is also found in Old French.[4]
Semantic evolution
With bois, forêt displaced Old French selve, from Latin silva, which survives only in place names.[2][5] From the 14th century it is used figuratively of a dense mass of upright things, as forest dez lanches, a forest of lances,[4][3] and later of the timbers of a roof (1690).[3] Phrases include les Eaux et Forêts (1690), forêt vierge (1845) and les arbres cachent la forêt “one cannot see the wood for the trees”.[3]
The derivative forestier (12th century) keeps the /s/ of the legal language.[5]
