Faerie, Fey, and Fae.

Can we can some consistency or clarification with these 3 terms? Are they all referring to the same beings? Are Fey/Faeries/Fae the same things?

Do Faeries use Fae Aether but Fey is an adjective to describe something as Fae-like or Fae-born? Or is it possessive, where "Fey Blessing" might be like Blessing of the Fae, sort of like how we don't say Japan food we say Japanese. Then in that case Fey would be like Fae-ese or possessive of Voeburt is Voeburtian, so something relating to The Fae is Fey?
