Five years ago, Jacques Lezra was asked to translate a book of untranslateable words. “The project provided me, and my co-editors,” he writes, “with a vivid sense of the history of how people think, and how societies think differently from one another.” This week, the fruits of their labor were published by Princeton University Press, and to celebrate the occasion, the publisher has released six PDFs of sample entries: begriff, kitsch, media, polis, right, and saudade.
