Wiktionary:Wikimedia language codes

Most Wikimedia Foundation (WMF) wiki projects have equivalent editions for different languages, with web addresses in the format: [language code].[WMF project name].org. Each language is usually represented by a ISO 639-1 or ISO 639-3 code. For example, the code for English is en, then en.wiktionary.org is the English Wiktionary and en.wikipedia.org is the English Wikipedia. Similarly, the code for French is fr, then fr.wiktionary.org is the French Wiktionary and fr.wikipedia.org is the French Wikipedia.

However, not all languages are coded by ISO. When new language editions of Wikimedia projects are introduced and there are no ISO codes for them, WMF Language Committee creates their own language codes.

The full list of Wiktionaries can be found at Wiktionary and the list of existing active Wikimedia codes not coded by ISO can be found at the following table:

Note: This list should not be confused with the list of languages that are used in the English Wiktionary but are not represented by individual ISO 639-1 or ISO 639-3 codes. See Languages without ISO codes.
