2231: petticoat, cotillion, and cotte Jan 23, 2021
As mentioned, the word 'coat' comes from the French 'cotte', but this is not the only word derived from it in English. Now obsolete in French opting for 'manteau', it is really only found in the phrase cotte de mailles (chainmail). That said, it also gave rise, somewhat unsurprisingly, to 'petticoat' (though now this describes a type of skirt, it was once an undercoat, but also to 'cotillion', a type of dance. Cotillion, which once had the same meaning as 'petticoat' i.e. 'small coat', now has the sense of referring to any formal dance-event, but in the 17th century referred to a specific dance in which one would raise her dress enough to display the petticoat.
