- Old French · derived fromGornai
- English todayGournay-en-Bray
From French, attested as Old French Gornai in 1049. * The first element is probably of Celtic origin, from Proto-Celtic *gorn (“fishery, reach”) + *-ako, Latinized as Latin -acum. * The second element was added in 1962 to avoid confusion with Gournay-le-Guérin in the department of Eure. It references Pays de Bray and is of Celtic/Gaulish origin, from *braco, for which see braye (“mud, daub”).
