четыре (Russian)
Where does "четыре" come from?
The Russian word for four, 'четыре' (chetyre), traces its roots back to the ancient Proto-Indo-European term *kʷetwóres. As the language evolved, it passed through Proto-Balto-Slavic and Proto-Slavic stages before reaching Old East Slavic, maintaining its consistent meaning throughout history. This ancient numeric root remains a linguistic cousin to similar words found in Sanskrit and various Iranian languages.
