EtymologyAuer is a German surname derived from the noun Aue, meaning "meadow by a river, wetland". The etymology traces back to Old High German ouwa, which refers to a meadow, floodplain, or land by a stream. As a topographic surname, it often originated from individuals who lived near such a landscape, such as a marsh or water meadow.In some cases, Auer may also be a habitational name derived from the many place names Au or Aue found in German-speaking regions. One notable location sharing the name is the municipality of Auer in South Tyrol, Italy; the town is also known by its Italian name, Ora.VariantsA simple variant of Auer is Aue, which is also a topographic surname from the same root. While Auer is the more common form, both surnames reference similar geographic features.DistributionThe surname Auer is found primarily in Germany and Austria, as well as in other areas where German-speakers have settled. Migration has brought the name to the United States and other English-speaking countries since the 19th century. The frequency of the name in each region reflects historic patterns of emigration from the Germanic territories of central Europe.Meaning: "meadow by a river, wetland"Origin: GermanType: Topographic surnameUsage regions: Germany, Austria, Italy, United States
