Forms
fondement m (plural fondements)[1] Old French fundement;[2] the Anglo-Norman spellings include fundament and foundement.[3]
Etymology
It is borrowed from Latin fundāmentum (“foundation, base, support”),[2][4][5] a derivative of fundō (“to found”), the source of fonder.[4][6] Bloch and Wartburg note that the word stayed in contact with written Latin;[6] the sense “anus” comes from medical Latin, where the Latin word had it in Late Latin.[4][6][2]
Cognate with Italian fondamento, Old Occitan fondamen, Catalan fonament and Spanish fundamento.[6][7][8]
Earliest recorded meaning
The first record, as fundement in Philippe de Thaon's Comput (1119), has the sense “anus”; the architectural sense follows about 1120 in the Oxford Psalter.[2]
Semantic evolution
In building, fondement named the masonry on which a structure rests (about 1120); this use is now old-fashioned, and fondation has replaced it.[4][2] By extension it came to mean whatever something rests on, from about 1174–1176,[2] and in particular the ground of a body of knowledge or a belief, as in sans fondement “groundless”.[4] The plural les fondements is used metaphorically for the bases of an institution, from about 1265 (Jean de Meun).[4][9]
The sense “buttocks, anus” survives as a rare euphemism, like derrière.[4] The English fundament comes from the Old French word.[10]
