Yggdrasil - Name

Name

The generally accepted meaning of Old Norse Yggdrasill is "Odin's horse", even with both the Poetic Edda and Prose Edda defining "Odin's Horse" to actually be Sleipnir instead. This conclusion is drawn on the basis that drasill means "horse" and Ygg(r) is one of Odin's many names. The Poetic Edda poem Hávamál describes how Odin sacrificed himself by hanging from a tree, making this tree Odin's gallows. This tree may have been Yggdrasil. Gallows can be called "the horse of the hanged" and therefore Odin's gallows may have developed into the expression "Odin's horse", which then became the name of the tree.

Nevertheless, scholarly opinions regarding the precise meaning of the name Yggdrasill vary, particularly on the issue of whether Yggdrasill is the name of the tree itself. In the Prose Edda the tree is usually not just called Yggdrasil but askr Yggdrasils. Old Norse askr means "ash tree" and according to the inflectional system of Icelandic language askr Yggdrasils means "Yggdrasill's ash". Icelandic has the best preserved inflectional system of the Norse languages and the Prose Edda was also written in old Icelandic. These etymologies do though rely on a presumed but unattested *Yggsdrasill.

A third interpretation, presented by F. Detter, is that the name Yggdrasill refers to the word yggr ("terror"), yet not in reference to the Odinic name, but rather as Yggdrasill as the "tree of terror, gallows". F. R. Schröder has proposed a fourth etymology according to which yggdrasill means "yew pillar", deriving yggia from *igwja (meaning "yew-tree"), and drasill from *dher- (meaning "support").
