Copied from Sindarin with only a few changes so far: initial ⟨i⟩ is not
special, ⟨qu⟩ exists, and ⟨y⟩ is a consonant.

This prepares the languages of Quenya and Sindarin, setting up their
infrastructure without declaring a lot of rules yet – just enough for
“Eä” (a Quenya word, but I can’t think of a similarly simple one for
Sindarin). Phonemes are inherited from Esperanto for now.
