Excerpt from "The TEXBook" by Donald Knuth: Insiders pronounce the X of TEX as a Greek chi, not as an 'x', so that TEXT rhymes with the word bleccchhh. It's the 'ch' sound in Scottish words like "lock" or German words lick "ach"; it's a Spanish 'j' and a Russian 'kh'.

Excerpt from "The TEXBook" by Donald Knuth: Hypens are used for compound words like 'daughter-in-law' and 'X-rated'. En-dashes are used for number ranges like 'pages 13-34', and also in contexts like 'exercise 1.2.6-52'. Em-dashes are used for punctuation in sentences--they are what we ofter call simply dashes. And minus signs are used in formulas.
