As the name of the Norse god of thunder, strength, and protection, it evokes images of power and resilience.

Meaning of Thor

The name Thor comes directly from Old Norse ‘Þórr’, which evolved from the Proto-Germanic word ‘*Þunraz’, meaning ‘thunder’. This etymology is exceptionally well-documented through ancient texts, runic inscriptions, and comparative linguistics across Germanic languages. In Old English, the related form ‘Þunor’ appears, while Old High German used ‘Donar’ for the same thunder deity. The name’s meaning is unequivocally tied to thunder and the associated Norse god, making it one of the most transparent mythological names in terms of linguistic origin and semantic content.

Thor originates from ancient Germanic mythology, specifically Norse mythology where Thor (Þórr) was the god of thunder, strength, protection, and hallowing. The name appears in numerous historical sources including the Poetic Edda, Prose Edda, and various runic inscriptions from the Viking Age. While the name has been adopted in Christian contexts in Scandinavia (where many traditional Norse names remained in use after Christianization), its fundamental origin is pre-Christian Germanic religion. The name spread through Viking expansion and later through literary works, becoming particularly popular in Iceland, Norway, Sweden, and Denmark.
