What Does the Name Rein Mean?
Rein means "counsel" or "advice," from the Germanic element ragin (also spelled regin). It is a Dutch and Estonian short form of compound names built with that element. The Dutch parent name Reinier comes from Raginhari, in which the second part means "army." The German name Reinhard comes from Raginhard, which joins ragin to hard ("hardy, brave"). Rein can also shorten other German names beginning with Rein-, such as Reinhold. As a short form, Rein carries the core sense of counsel rather than the full meaning of any one compound. The Dutch adjective rein, "pure," and the English noun rein, a horse's strap, are unrelated words that happen to share the spelling.
Rein Name History & Origins
Names built on ragin were used in medieval Germanic-speaking regions. Raginhard and Raginhari are the older forms that became German Reinhard and Dutch Reinier. In Dutch, Rein is used as a short form of Reinier. In German-speaking regions it shortens Reinhard or Reinhold. The name also took root in Estonia, where Rein is an established masculine name, usually understood as a short form of German-derived names such as Reinhard; this fits the long influence of German and Baltic German naming in Estonia.
