List of Wikipedias

Wikipedia projects vary in how they divide dialects and variants. For example, the English Wikipedia includes most modern varieties of English including American English and British English.[6][7] Similarly, the Spanish Wikipedia includes both Peninsular Castilian and Latin American Spanish,[8] and the Portuguese Wikipedia includes both European Portuguese and Brazilian Portuguese.[9] In contrast, some languages have multiple Wikipedias. For example, the Serbo-Croatian language encompasses four Wikipedia editions, Serbo-Croatian and three different standardized varieties (Bosnian, Croatian, and Serbian).[10]

Additionally, some Wikipedia projects apply different approaches to orthography. For instance, the Chinese Wikipedia automatically transliterates between six standard forms: three using simplified Chinese characters (Mainland China, Malaysia, and Singapore) and three using traditional Chinese characters (Taiwan, Hong Kong, and Macau).[11][12] And rather than relying on transliteration, Belarusian has separate Wikipedia projects for the official Narkamaŭka and Taraškievica orthographies.[13]

Each Wikipedia project has a code, which is used as a subdomain of wikipedia.org. The codes mostly conform to ISO 639-1 two-letter codes or ISO 639-3 three-letter codes, with preference given to a two-letter code if available.[14] For example, en stands for English in ISO 639-1, so the English Wikipedia is at en.wikipedia.org.
