# Cartograph Exonyms (what each country is called in 51 languages)

> See what a country is called in 51 languages, grouped into name families and mapped. Shows the name of a country in 51 languages (from Wikidata), writes every name in Latin letters and groups them into spelling families — Deutschland, Duitsland and Tyskland; Allemagne, Alemania and Almanya; Germania and Германия; Niemcy and Německo — and colours a map by the family each country’s main language uses. It is the exonym engine of the Cartograph app.

## Inputs

- region (select): Map

## Method
- Names: the Wikidata label of the country in each language (CC0), retrieved on 2026-11-14 — usually the short name, sometimes a longer official form.
- Latin letters: a letter table per script (Cyrillic, Greek, Georgian, Armenian, Hebrew, Arabic and Persian, Devanagari, Japanese kana, Korean Hangul by syllable). Chinese characters are not transliterated and stay ungrouped.
- Families: the first two consonant sounds after leading articles are removed and similar letters are merged (p/b/f/v/w, t/d/th, k/g/c/q/ch, s/z/sh/ts …). Names with the same key usually share a root, but the key is a spelling heuristic, not an etymology: unrelated names can meet and related ones can split.
- Map: each country whose main language is one of the 51 is coloured by the family of that language’s name; other countries stay grey. Natural Earth 1:110m outlines, small countries as dots.
