Kotoistus suosittelee käytettäväksi seuraavia suomenkielisiä nimityksiä kielistä (CLDR 44). Tällä sivulla ne on järjestetty kielen suomenkielisen nimen mukaan. Joillekin kielille tarjotaan myös rinnakkaista muotoa (kielikoodin jälkeen ”-secondary”) ja joillekin vaihtoehtoista lyhyttä muotoa (”-short”). Suositukset on päivitetty 29.2.2924.
Muilla sivuilla tiedot esitetään englanninkielisen nimen mukaan järjestetyssä taulukossa ja kielikoodin mukaan järjestetyssä taulukossa.
