Page "Don Quixote" Paragraph 39

In Old Castilian the letter x represented the sound written with sh in modern English, so the name was originally pronounced " ".

However as Old Castilian became modern Spanish, the pronunciation of the sh sound changed, and came to be pronounced with a voiceless velar fricative sound like the Scottish or German ch and today the Spanish pronunciation of " Quixote " is.

The original pronunciation is reflected in languages such as Astur-Leonese, Galician, Catalan, French, Italian and Portuguese that pronounce it with a " sh " or " ch " sound.
