As people moved to new lands over thousands of years, their one language slowly split into many. Picture a giant tree: the trunk is Proto-Indo-European, and each branch is a group of related languages. One branch grew into Hindi and Sanskrit, another into English and German, another into Spanish, French, and Russian. Today this single family has more than 400 living languages, and about half of all people on Earth speak one of them.
⚡ DID YOU KNOW?
English, Hindi, Spanish, Russian, and Persian are all cousins in the same family tree, even though they sound completely different.
