Gast

The name Gast is derived from the Old High German word 'gast' and the Proto-Germanic '*gastiz*', both meaning 'guest' or 'stranger'. It was primarily used as a surname, indicating someone who was a visitor, a newcomer to a community, or perhaps a host. Over time, like many surnames, it occasionally transitioned into use as a given name, though it remains far more common as a family name.

Its usage as a given name is exceedingly rare and often tied to specific family traditions or regional dialects where surnames were sometimes adopted as first names. The concept of 'guest' or 'stranger' could also imply hospitality or a journey, though these connotations are less prominent in its direct etymology.
