Valarin

Valarin is the tongue of the Ainur. As angelic beings with the ability to communicate through thought, strictly speaking the Valar had no need for a spoken language, but it appears that it was adopted as part of their assumption of physical, humanlike forms.

Valarin was extremely alien to the ears of the Elves, sometimes to the point of genuine displeasure, and very few of them ever learned the language, only adopting some of the Valarin words into their own Quenya. The Valar learnt Quenya instead, and used that to converse with the Elves, or with each other if Elves were present. Valarin seemed to use long words, for example the Valarin word for Telperion, Ibrîniðilpathânezel is eight syllables long. The Vanyar adopted more words from Valarin into their dialect Quendya than the Noldor, as they lived closer to the Valar.

At least one word in the Black Speech, nazg "ring", seems to be borrowed from Valarin na
