Elfish

The Elfish language was spoken by the Elves, a humanoid race on Ifreann.

There were in fact several Elfish languages, but they were derived from a common ancestor several millennia before Brianna Barter's birth. It's a subtle language. For instance, Theau Lunea means literally "shining moon", but figuratively means "thank you".

Unereif apparently means southeast.

A number of books have been written on the Elfish language, and Brianna Barter as Bellany Norwit studied it at Vargrend's; in class with Mrs. Dejan, as well as from her helf-elven fencing instructor Trinidar Leafwhisper.
