It is hardly a year ago since the Tango reached this country from South America by way of Paris. It was at first no more than a music-hall freak. But some of those mysterious people who inspire new social fashions were attracted by its sinuous movements and the strange backward kick, and this year it made its way into private houses as well as public ball rooms. [The Living Age, Dec. 13, 1913]



"I need not describe the various horrors of American and South American negroid origin. I would only ask hostesses to let one know what houses to avoid by indicating in some way on their invitation cards whether the 'turkey-trot,' the 'Boston' (the beginner of the evil), and the 'tango' will be permitted." [quoted in "Current Opinion," October 1913, as from a letter to the London Times]
tangram (n.)youdaoicibaDictYouDict
Chinese geometric puzzle, 1864, said to be an arbitrary formation based on anagram, etc. First element perhaps Chinese t'an "to extend," or t'ang, commonly used in Cantonese for "Chinese." Some suggest it is the name of the inventor, "but no such person is known to Chinese scholars" [OED]. Another theory involves the Tanka, an outcast aboriginal people of southern China, and Western sailors who discovered the puzzle from their Tanka girlfriends. Perhaps from an obscure sense of tram. The Chinese name is Ch'i ch'iao t'u "seven ingenious plan."
