Category:Languages by international organization

This category is incomplete and contains only the working languages used by major international organisations: you can look Languages by country or region, Languages by code or Languages by family instead if you don't find your language in the organisations listed here. You may also want to search them in ISO 15924, i.e. grouped by the standard code of scripts in which they are commonly written.

Please help categorizing your languages consistantly (most major languages or languages spoken in multiple countries have already been categorized), first by family and then by country or region (official or majority languages recognized in each country or one of its subdivision should be subcategorized specifically), as well as by their writing script and, where appropriate, by international organization of which these countries are members or observers.
