The French alphabet is pronounced similarly to the English alphabet, with a few differences in terms of pronunciation of certain letters. Some letters in the French alphabet have unique sounds, such as "r," "u," and "e." It is important to listen to native French speakers to properly learn the pronunciation of the French alphabet.

English uses the Latin alphabet of the Romans. However, this had no letter suitable for representing the phoneme /w/ which was used in Old English, though phonetically the sound represented by /v/ was quite close. In the 7th century scribes wrote uu for /w/; later they used the runic symbols known as wynn. European scribes had continued to write uu, and this usage returned to England with the Norman Conquest in 1066. Early printers sometimes used vv for lack of a w in their type. The name double-u recalls the former identity of u and v, which is also evident in a number of cognate words (flour/flower, guard/ward, suede/Swede, etc.).(Oxford Companion to the English Language)
