Heh. Slate writes about Enya:
On Amarantine, though, there's a different kind of linguistic stunt. Inspired by their Fellowship of the Ring experiment with Elvish, Enya and Roma Ryan decided to create their own language, Loxian. I wish I could report that this gambit involves smoked salmon; in fact, it revolves around the more banal topic of extraterrestrials. The Loxians, Ryan told the Guardian, "Are much like us. They're in space, somewhere in the night. They're looking out, they're mapping the stars, and wondering if there is anyone else out there. It's to do with that concept: are we alone in the universe?"
Ryan has written a book about the language, Water Shows the Hidden Heart (also the title of a song on Amarantine), in which we learn, among other things, how to ask a Loxian if he'd like a cup of tea ("Hanee unnin eskan?"). The lyricist claims that it was necessary to invent an alternative language because "some pieces that Enya writes, English will just not sit on." But judging by songs like "Less Than a Pearl," one of three Loxian numbers on the new album, Loxian is not appreciably more mellifluous than English or Gaelic or Latin or any of the other terrestrial tongues in which Enya has sung. I suspect other, cheekier motives: an effort to deepen Enya's reputation as a mystic and to tighten her grip on the Hobbit crowd. What's Loxian for "brand extension"?
I have an image of Enya babbling like Nell.
Though, to be fair, Liz Fraser might as well have been singing in Loxian for most of the Cocteau Twins catalog.
