How to pronounce
Yggdrasil

Yggdrasil is a Norwegian mythical tree of life that has an important role in Norse Mythology. In Norse mythology, it is described as a large ash tree that the gods visited to assemble as a governing body.
The name Yggdrasil (Yggdrasill in Old Norse) is generally purported to mean Odin's horse, which is said to refer to the gallows from which Odin is said to have sacrificed himself by hanging.
The pronunciation of the word Yggdrasil in Norse can be approximated as eeg-drah-sil, where the "i" in -sil approaches the sound of an abbreviated "ea", like in the word "seal".
