dos (Spanish)

Where does "dos" come from?

The Spanish word "dos" traces its ancestry back to the Proto-Indo-European *dwóh₁, a root meaning "two" that has left its mark on languages across the globe. From its Proto-Indo-European origins, it evolved through Proto-Italic into the Latin "duōs" and eventually into Old Spanish. This ancient numerical concept remains remarkably consistent today, sharing deep linguistic roots with cognates like the English word "two."
