Indo-European language

This map shows the spread of Indo-European speakers, according to the theory their original home was in Anatolia.

Linguists link most of the languages spoken in Europe today through shared word roots, even though most of those languages can no longer be understood by speakers of the other related languages. The Celtic languages, the Romance languages, the Slavic languages, and the Germanic languages can all be linked to some of the languages now spoken in India, like the Sanskrit language.

Languages spoken in Europe, today, that are not linked to the Indo-European languages include the Basque language, Hungarian, Turkish, and the Finnish language. Lost languages, like the Estruscan language, are also suspected of being from outside the indo-European group.
