dous (Galician)

Where does "dous" come from?

The Galician word 'dous' traces its origins back to the ancient Proto-Indo-European term *dwóh₁, which expressed the concept of 'two' in its unique dual grammatical form. It evolved through Proto-Italic and Latin as 'duōs' before settling into Old Galician-Portuguese, eventually becoming the modern word used today.
