@bakia,
Slavic, Turk, Latin, Germanic, Hebrew might as well be considered one. it is unchanged as of recorded history, and then there is the India varieties, and Chinese Varieties, African Varieties..
Slavic, Turk, Germanic and Latin are the four ancients of Europe.
However, strikingly Fin, Estonian, Latvian and Lithuanian are not covered by any of these surrounding ancient tongues, nor are they similar to one another.
Turk covers a variety of languages from Greece to the Himalayans- just North of the Arabic language sector. Farsi may be considered a turk language. Georgian IS a turk language despite its incredibly unique alphabet.
Kazakhstan, the worlds 7th largest country, prominent for it's English university/colleges, ex Russian government and Russian language presence, has a national language which is of a Turk dialect.
India, having over 10 languages.. is like Europe, more than a country. a union. China is the same way. they both have more languages than you would ever find out existed if you lived there your entire life.
Every heard of Galician? it is a Spanish province which speaks a hybrid of Spanish Portuguese.
