Apart from the fact that I like the sound of the name I also like the meaning “Tree of life” or “Tree of Wisdom”
While working with horses you can never say you know it all, it is a life’s journey. It is like the growth of a tree, never straight but branching out, ever changing but yet always the same.
Here is what Wikipedia has to say on Yggdrasil:
“In Norse mythology, Yggdrasil (from Old Norse Yggdrasill IPA: [ˈyɡːˌdrasilː]; meaning “Ygg’s (Odin’s) horse”) is the world tree.
Yggdrasil is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources; and the Prose Edda, written in the 13th century by Snorri Sturluson. In both sources, Yggdrasil is an immense ash tree that is central and considered very holy.
The Æsir go to Yggdrasil daily to hold their courts. The branches of Yggdrasil extend far into the heavens, and the tree is supported by three roots that extend far away into other locations; one to the well Urðarbrunnr in the heavens, one to the spring Hvergelmir, and another to the well Mímisbrunnr. Creatures live within Yggdrasil, including the harts Dáinn, Dvalinn, Duneyrr and Duraþrór, and an unnamed eagle, and the wyrm Níðhöggr. Scholarly theories have been proposed about the etymology of the name Yggdrasill, the potential relation to the trees Mímameiðr and Læraðr, and the sacred tree at Uppsala.
Opinions regarding the meaning of the name Yggdrasill vary, particularly on the issue of whether Yggdrasill is the name of the tree itself, or if only the full term askr Yggdrasil refers specifically to the tree. Yggdrasill means “Ygg’s horse”, “Yggr” is one of Odin’s many names, and according to this, askr Yggdrasils would be viewed as the world-tree upon which the “horse of the highest god is bound”.
The generally accepted etymology of the name is that Yggdrasill means “Odin’s horse”, which means “tree”, and that the reason behind the name “Odin’s horse” lies in the notion of gallows as “the horse of the hanged”, and, according to this notion, the tree would then be the gallows in which Odin hanged during his self-sacrifice described in the Poetic Edda poem Hávamál. Both of these etymologies rely on a presumed but unattested *Yggsdrasill.
A third interpretation by F. Detter is that the name Yggdrasill refers to the word Yggr (“terror”), yet not in reference to the Odinic name, and so Yggdrasill would then mean “tree of terror, gallows”. F. R. Schröder has proposed a fourth etymology where yggdrasill means “yew pillar”, deriving yggia from *igwja (meaning “yew-tree”), and drasill from *dher- (meaning “support”).
