Excerpt from Tiffany Watt Smith's Schadenfreude: The Joy of Another's Misfortune (Little, Brown and Company, 2018):
The Japanese have a saying: "The misfortunes of others taste like honey." The French speak of joie maligne, a diabolical delight in other people's suffering. The Danish talk of skadefryd, and the Dutch of leedvermaak. In Hebrew enjoying other people's catastrophes is simcha lau2011ed, in Mandarin xìngu2011zu0101iu2011lèu2011huò, in Serbo-Croat it is zlùradu014dst and in Russian zloradstvo. More than 2,000 years ago, Romans spoke of malevolentia.
