What is the meaning of the name Reidur ?

Reidur is Norse, Scandinavian in Origin.

Reidur is a Nordic masculine name, most plausibly an anglicized or Icelandic-influenced spelling of Reidar, ultimately from Old Norse Hreiðarr. The first element hreiðr means “nest, home,” paired with -arr “warrior,” yielding senses like “home-guardian” or “warrior of the homestead.” The -ur ending matches common Icelandic masculine nominatives, which likely encouraged this spelling in modern records.

Attested as Hreiðarr in saga-era sources, the name survives chiefly as Reidar in Norway and Sweden, where it peaked in the mid-20th century; Iceland uses Hreiðar sparingly today. Reidur itself is rare and appears in diaspora or transliterated contexts. Notable variants and cognates include Reidar (Norwegian, Swedish), Hreiðar (Icelandic), Reiðar (Faroese), and the simplified Reid in modern usage, though Scottish Reid (“red-haired”) is etymologically unrelated. Short forms such as Rei occur informally. Overall, Reidur offers a traditional Norse heritage with a distinctive, streamlined look.
