(as access to the OED online is not free, the relevant excerpt is provided) "Littré's theory, that there was already in 17th c. a French contre-danse with which the English word was confused and ran together, is not tenable; no trace of the name has been found in French before its appearance as an adaptation of the English. But new dances of this type were subsequently brought out in France, and introduced into England with the Frenchified form of the name, which led some Englishmen to the erroneous notion that the French was the original and correct form, and the English a corruption of it."
