Early Quenya

Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
An (impersonal?) verb appearing as ᴱQ. vildin “it matters, is of significance, worth, moment” in the Qenya Lexicon of the 1910s under the early root ᴱ√VḶŘḶ [VḶÐḶ] (QL/102).
Neo-Quenya: For purposes of Neo-Quenya, I would adapt this verb as ᴺQ. valda- “to matter; to be of significance, worth, moment” based on a Neo-Root ᴺ√BALAD.
