Pronounced as (IPA)

[ˈkʷat.tu.ɔr]

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. One theory suggests contamination with *kʷtwr̥- (zero-grade form).
