Etymology

From the Anglo-Norman surname (de) Warenne, a reference to a place called Varenne, a hamlet near Arques-la-Bataille, along the river Varenne in Normandy, from Medieval Latin Warinna, a hydronym of Celtic/Gaulish origin, from var-, ver- (“river, water”), ultimately from Proto-Indo-European *h₂wer- (“water, rain, flow”); see also the Latin river Avara. Phonetic Germanic influence is shown by the [v] > [w].
