Ruis

Ruis is a term used in several different contexts. In Finnish, ruis is the word for rye, the cereal grain that forms the basis of a traditional Nordic pantry. Rye is known for its dense crumb and distinctive flavor and is used to make breads such as ruisleipä as well as rye flour and other baked goods.

Ruis as a surname appears in European records, and in some cases may derive from Dutch or Flemish roots, possibly as a variant of surnames such as Ruys or Ruijs. In genealogical sources it is found among families in the Netherlands and surrounding regions, with bearers involved in diverse professions.

Beyond language and naming, Ruis may surface in toponymy, branding, or fiction, reflecting the cultural reach of rye and related heritage. There is no single widely recognized meaning or entity that carries the name globally; rather, Ruis functions as a lexical item, family name, or place name in various locales.
