List of Latin-script alphabets



The lists and tables below summarize and compare the letter inventories of some of the Latin-script alphabets. In this article, the scope of the word "alphabet" is broadened to include letters with tone marks, and other diacritics used to represent a wide range of orthographic traditions, without regard to whether or how they are sequenced in their alphabet or the table.

Parentheses indicate characters not used in modern standard orthographies of the languages, but used in obsolete and/or dialectal forms.

Alphabets that contain only ISO basic Latin letters
Among alphabets for natural languages the English,[36] Indonesian, and Malay alphabets only use the 26 letters in both cases.

Among alphabets for constructed languages the Ido and Interlingua alphabets only use the 26 letters, while the Toki Pona uses a 14-letter subset.

Extended by ligatures

 * German (ß), Scandinavian (æ)

Extended by diacritical marks

 * Spanish (ñ), German (ä, ö, and ü)

Extended by multigraphs

 * Filipino (ng)

Alphabets that contain all ISO basic Latin letters
Among alphabets for natural languages the Afrikaans,[54] Aromanian, Azerbaijani (some dialects)[53], Basque,[4] , Celtic British, Catalan,[6] Cornish, Czech,[8] Danish,[9] Dutch,[10] Emilian-Romagnol, Filipino,[11] Finnish, French,[12] , German,[13] Greenlandic, Hungarian,[15] Javanese, Karakalpak,[23] Kurdish, Modern Latin, Luxembourgish, Norwegian,[9] Oromo[65] , Papiamento[63] , Polish<sup style="font-size:80%" id="r-pl">[22] , Portuguese, Quechua, Rhaeto-Romance, Romanian, Slovak,<sup style="font-size:80%" id="r-sk">[24] Spanish,<sup style="font-size:80%" id="r-es">[25] Sundanese, Swedish, Tswana,<sup style="font-size:80%" id="r-tn">[52] Uyghur, Venda,<sup style="font-size:80%" id="r-ve">[51] Võro, Walloon,<sup style="font-size:80%" id="r-wa">[27] West Frisian, Xhosa, Zhuang, Zulu alphabets include all 26 letters, at least in their largest version.

Among alphabets for constructed languages the Interglossa and Occidental alphabets include all 26 letters.

The International Phonetic Alphabet (IPA) includes all 26 letters in their lowercase forms, although g is always single-storey (ɡ) in the IPA and never double-storey.

Alphabets that do not contain all ISO basic Latin letters
This list is based on official definitions of each alphabet. However, excluded letters might occur in non-integrated loan words and place names.

The I is used in two distinct versions in Turkic languages: dotless (I ı) and İ|dotted (İ i). They are considered different letters, and case conversion must take care to preserve the distinction. Irish traditionally does not write the dot, or tittle, over the small letter i, but the language makes no distinction here if a dot is displayed, so no specific encoding and special case conversion rule is needed as it is for Turkic alphabets.

Statistics
The chart above lists a variety of alphabets that do not officially contain all 26 letters of the ISO basic Latin alphabet. In this list, one letter is used by all of them: A. For each of the 26 basic ISO Latin alphabet letters, the number of alphabets in the list above using it is as follows:

Letters not contained in the ISO basic Latin alphabet
Some languages have extended the Latin alphabet with ligatures, modified letters, or digraphs. These symbols are listed below.

Other letters in collation order
The tables below are a work in progress. Eventually, table cells with light blue shading will indicate letter forms that do not constitute distinct letters in their associated alphabets. Please help with this task if you have the required linguistic knowledge and technical editing skill.

For the order in which the characters are sorted in each alphabet, see collating sequence.
