Here's an interesting pair of letters from the Jewish Chronicle; the first is dated 10.25.1957, the second 11.11.1957. Interesting because it concerns Rashi's bing called Yarchi, and Ibn Ezra "Aben" Ezra. There's more to say about this, especially about Yarchi (which will have it's own post eventually), but also about Spinoza and Hebrew. But the day is short. See this post about pronouncing "ibn." The first guy was a famous chess player, by the way.
