How to read the map. Each colour is a language family: a group of languages that share a common ancestor. The ten largest families have their own colour and every other family is grey. Areas are see-through, so where two languages share a place the colours mix. Tap anywhere to list every language whose area covers that spot. Areas are generalisations drawn from published atlases, many of them decades old, and cities are multilingual, so an area never says that everyone there speaks the language. A dot marks a language that has no area map. The family name is always given in words, because colour alone is hard to tell apart for some people.

On the map, Sui is drawn as an area from Asher and Moseley 2007. The area was digitised by the Glottography project (doi:10.5281/zenodo.18613195), and the atlas is cited on the data sources page. Language areas are generalisations, and cities and borderlands are multilingual, so the outline does not mean that everyone inside it speaks Sui.
