Latin-derived Alphabet

A Latin-derived alphabet is an alphabet that uses letters from the Latin script, which comprises the original Roman Latin alphabet and various extensions. Extension can be by adding diacritics to existing letters, joining multiple letters together to make ligatures, creating completely new forms, or assigning a special function to pairs or triplets of letters.

These new characters are often given a place in the alphabet by defining an alphabetical order or collation sequence, which can vary with the particular alphabet. Some, especially those with diacritics, are not considered distinct letters: French é and German ö, for example, are not used in the commonly quoted alphabet sequences.

The ISO basic Latin alphabet is the best-known Latin script based alphabet. The International Phonetic Alphabet is also Latin-derived.

The tables below summarize and compare some of the alphabets. In this article, the word "alphabet" is intentionally broadened to include letters with tone marks and other diacritics used to represent a wide range of orthographic traditions found in modern and classical literature, without special regard as to whether the modified letters have their own traditional alphabetic place or are interfiled, or whether the letters are in the sequence in the table or elsewhere. Peculiarities of the particular alphabet in question may be noted in footnotes, in other Wikipedia articles, or elsewhere on the Internet.
