Etymology
It is borrowed from French flanc (“flank, side of the body”), first as a military term.[2][3][4][1] Bluteau already explained it as a term of fortification taken from the French word for the side of an animal, especially of a horse.[5]
The French word goes back to Frankish *hlanka (“hip; side of the body”).[2][6] The DHLF thinks it was remade around 1080 on the older Old French flanche.[6] The Frankish word has cognates in Old High German hlanca (“hip”), Old Saxon hlanka (“hip, thigh”) and Old Norse hlekkr (“link”), from Proto-Germanic *hlankaz (“flexible, bent”).[7][1] A root Proto-Indo-European *kleng- (“to bend”) has been proposed, though the word has no certain cognates outside Germanic.[1]
Older dictionaries derived it from Latin flaccus (“flabby”), an explanation Nascentes reports and rejects.[8][9] Gonçalves Viana held it to be a Gallicism that was Portuguese only as a term of tactics.[10] Spanish flanco was borrowed from French too, about 1700, also as a term of war, heraldry and fortification.[11]
Semantic evolution
Houaiss's first date, 1649, is for the military sense.[2] The dictionaries of the 18th century know only the fortification, the part of a bastion between its face and the curtain wall.[5][12] Vieira adds the side of a line of troops.[13] The original Caldas Aulete has the side of the human and animal body, the side of a ship, a woman's womb, and the weak or accessible point, as in dar flanco.[14] Football, geology and engineering have since taken the word for a side or slope of anything.[2][15]
