Proto-Indo-European to modern tongues — trace the roots of human language
There are roughly 7,000 living languages in the world, grouped into about 142 distinct language families. Indo-European is the largest by native speakers — around 3.2 billion — while Sino-Tibetan comes second with about 1.3 billion, largely thanks to Mandarin, the world's most-spoken first language.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore the contested Proto-Indo-European homeland (Kurgan vs Anatolian hypotheses), Niger-Congo's vast reach, Austronesian's stretch from Madagascar to Easter Island, language isolates like Basque, the looming crisis of endangered languages, and the role of Sanskrit in the birth of comparative linguistics.
By number of native speakers, Indo-European is the largest with about 3.2 billion speakers, including English, Spanish, Hindi, and Russian. By number of distinct languages, however, Niger-Congo leads with roughly 1,500 languages spread across sub-Saharan Africa.
Linguists use the 'comparative method,' matching cognate words across related languages to reconstruct earlier sound systems and vocabulary. This method, developed in the 19th century, yielded reconstructions like Proto-Indo-European and relies on regular sound correspondences such as Grimm's Law.
Languages die when their remaining speakers shift to a more dominant tongue, driven by colonization, urbanization, schooling, and media. UNESCO estimates that about one language dies every two weeks, and roughly 43% of the world's languages are endangered.
