Etymology: From Latin invidiosus, envious, hostile, from invidia, envy.
"I felt particular interest in watching the combustion of American authors, and scrupulously noted by my watch the precise number of moments that changed most of them from shabbily printed books to indistinguishable ashes. It would be invidious, however, if not perilous, to betray these awful secrets; so that I shall content myself with observing that it was not invariably the writer most frequent in the public mouth that made the most splendid appearance in the bonfire" ("Earth's Holocaust" in Mosses from an Old Manse, Nathaniel Hawthorne, 1846).
