Unrelated, but, IIRC, Tolkien (whom one could perhaps regard as a language connoisseur) had a peculiar taste for languages, and Welsh was in fact his favorite?
He had particular affection for Welsh and Finnish, from what I remember. His academic specialty was Old English.
He must have really liked long words!
I believe Welsh was one of the main inspirations behinds his elvish conlang Sindarin.
