Walle

The name Walle is a short form or diminutive of various Germanic names containing the element *walha-, meaning 'foreigner' or 'stranger'. This root is also the origin of the word 'Welsh' (referring to the people of Wales, who were seen as foreigners by the Anglo-Saxons) and 'Walloon' (a Romance-speaking people in Belgium). The name has been used in various forms across Germanic-speaking regions.

Historically, names derived from this root were often given to people who were not of the dominant Germanic tribe, or to those who had come from Romanized areas. Over time, it evolved into surnames and given names, particularly in Northern Europe. Its usage as a standalone given name is less common than its longer forms or as a surname.
