If you've ever encountered the ligatures æ and œ in old texts, you may have wondered: what are they called? Where do they come from? How exactly are they pronounced? Why don't we use them any more? The ligatures ash and ethel are rare in English writing today, but in previous centuries, they were common. (In Old English, the sound we today associate with "short A" was actually not represented by the letter A, but by æ!)
