Biscarosse, the birthplace of Aéropostale, is said to have a Basque name. Bizkar refers to the "back" in Basque and would be followed by the Aquitaine augmentative –os. In the same way, Urdos would come from the Basque urd, plateau. From these two toponyms, we will theorize that the toponyms in –os belong to a very ancient Aquitarian family. However, developing a theory based on only two toponyms, when there are more than 200 toponyms in –os, does not seem very scientific. It turns out that Biscarosse could also correspond to the name Viskarr, which gave the names Guiscard (60) and Giscard (11, 12), but also Giscaro (32), Giscours (33) and Visker (65). As for Urdos, anc. Hurdos, this name would be compared to Ourdes (65), Ourdis (64), Ourdous (64), Hordosse (47), but also Hourtin (33) and Ordeville (85). The radical would correspond to the Nordic name Hord (pronounced Hourd). The Basque origin of Urdos and Biscarosse is questionable, so it is the whole thesis of pre-Aquatrianic toponyms in –os that becomes it. If we add that 90% of toponyms in –os have an identifiable Scandinavian name for their radical... the probabilities are clearly in favor of a Norse origin.
