Meaning & usage
two
Where this word comes from
From a Vulgar Latin *duī (“two”, root), from Latin duo, probably formed through analogy with the usual nominative masculine plural ending in -ī. Ultimately from Proto-Italic *duō, from Proto-Indo-European *dwóh₁. The similar formation of *duī also happened in Old French dui, nominative form of deus. Compare Italian due, Sicilian dui, Friulian doi.
