Overview
Mauger is a Norman surname of Germanic origin (possibly meaning 'council-spear'). It was used first as a given name in the Middle Ages. pronunciation API : French [moʒe] (Old French [maʷdʒɘʁ]) ; English [ˈmeɪ.dʒ.ə(ɹ)].
Etymology
The second element of the name -ger is from Germanic gari "spear" (see Roger, Gerard, etc.), while the first element Mau-, is a short form for Madal-, which is ultimately from Germanic *maþl- "assembly, council" (Old High German mahal, Anglo-Saxon mæðl "council, assembly"). The Old Norman form was Malger. In fact, it could recover an Old Scandinavian given name, like many other Norman first names (Anfray, Angot, etc.) in the Middle Ages. The Old Norse form for madal was mál "speech, law-suit" and the given name was perhaps *Málgeir, which has survived as Málgeir in Icelandic, if it is not a new created name. The Old Danish nickname Malti could be related to it, as a short form of the Germanic names beginning with Madal-. The given name Malte originates from it.
In the old documents, it was Latinized different ways such as Maugerius, Malgerius, Maldegarius, Madalgarius. Old French Malger and Middle French Maugier are often found.
