Language Families
How the world's thousands of tongues group into a few great families — with the vast Indo-European family broken into its major branches.
Each school is a star; the threads trace teachers to their heirs.

All schools by tradition
Human language
- ~7,000 living tongues
The roughly seven thousand languages spoken today group, by shared descent, into a few dozen families. Each branch below gathers tongues that trace back to one ancestral speech.
Indo-European
- ~3.2 billion speakers
from Human Language
The world's largest family by speakers, descended from a single prehistoric tongue once spoken on the Eurasian steppe. It spread from Europe to India in many great branches.
- English · German · Dutch · Nordic
from Indo-European
The branch of English, German, Dutch, and the Scandinavian tongues. Carried worldwide by trade and empire, English became the first truly global lingua franca.
- from Latin
from Indo-European
The daughters of Latin — Spanish, Portuguese, French, Italian, and Romanian — spread by Rome and later by colonisation across the Americas and beyond.
- Russian · Polish · Czech · Serbian
from Indo-European
The East, West, and South Slavic tongues of Eastern Europe and Russia, including Russian, Polish, Czech, and Serbian — many written in the Cyrillic script.
- Hindi · Persian · Bengali · Urdu
from Indo-European
The easternmost and most populous branch — Sanskrit's heirs in India (Hindi, Bengali, Urdu) and the Iranian tongues (Persian, Kurdish, Pashto).
- Greek · 34+ centuries
from Indo-European
Essentially Greek alone, but with the longest documented history of any Indo-European tongue — the language of Homer, philosophy, and the New Testament.
- Irish · Welsh · Breton
from Indo-European
Once spread across much of Europe, now surviving on its Atlantic fringe — Irish, Scottish Gaelic, Welsh, and Breton, kept alive by revival movements.
- Lithuanian · Latvian
from Indo-European
A small branch of just Lithuanian and Latvian, prized by linguists because Lithuanian preserves archaic features close to the reconstructed Indo-European parent.
Sino-Tibetan
- Chinese · Tibetan · Burmese
from Human Language
The family of Chinese, Tibetan, and Burmese and hundreds of related tongues. Chinese alone, with over a billion speakers, is the world's most spoken first language.
Afro-Asiatic
- Arabic · Hebrew · Amharic
from Human Language
Spanning North Africa and the Middle East, this family includes the Semitic tongues (Arabic, Hebrew, Amharic) as well as ancient Egyptian and the Berber languages.
Niger-Congo
- Swahili · Yoruba · Zulu
from Human Language
Probably the largest family by number of languages, covering most of sub-Saharan Africa. Its Bantu sub-group alone — Swahili, Zulu, Shona — spans the continent's south.
Austronesian
- Malay · Tagalog · Malagasy · Māori
from Human Language
Carried by seafarers across half the globe, from Madagascar to Easter Island — Malay, Indonesian, Tagalog, Hawaiian, and the Polynesian tongues.
Uralic
- Finnish · Hungarian · Estonian
from Human Language
A northern Eurasian family of Finnish, Estonian, Hungarian, and the Sámi tongues — non-Indo-European islands amid Europe's Indo-European sea.
Other families
- Tamil · Telugu · Kannada
from Human Language
The languages of southern India — Tamil, Telugu, Kannada, Malayalam — older in the subcontinent than the Indo-Iranian tongues that later spread from the north.
- Turkish · Kazakh · Uzbek
from Human Language
A closely knit family stretching from Turkey across Central Asia to Siberia — Turkish, Azerbaijani, Kazakh, Uzbek, and Uyghur among the largest.
- Japanese · Korean
from Human Language
Japanese (with the Ryukyuan tongues) and Korean each form small, largely isolated families, their deeper kinship still debated by linguists.
- Basque · Ainu · others
from Human Language
Tongues with no known relatives at all, such as Basque in Europe — living reminders of how many ancient language families have vanished without a trace.
