Etymology

From Proto-Italic *kʷettwōr (*t duplicated preceding *-w-), from Proto-Indo-European *kʷetwṓr, neuter plural of *kʷetwóres. Cognates include Sanskrit चतुर् (catur), Old Armenian չորք (čʻorkʻ), Ancient Greek τέσσαρες (téssares), and Old English fēower (English four).

The change of *e to a is unexplained; the expected form would be *quettuor.

• (Classical) IPA^(key): /ˈkʷat.tu.or/, [ˈkʷät̪ːuɔr]
• (modern Italianate Ecclesiastical) IPA^(key): /ˈkwat.tu.or/, [ˈkwät̪ːuor]
