A neologism for “leave, depart” coined by Elaran on 2023-07-02 in the Vinyë Lambengolmor Discord Server (VLDS), derived from *khay-nā and thus a verbal variant of hae “far”, originally “become distant”; compare also G. haithin “gone, departed” from the Gnomish Lexicon of the 1910s. Elaran proposed this verb to replace gwae- “to depart” for those who think that Tolkien discarded this irregular verb in his later notes. I prefer to retain gwae-, but I think it can coexist with haena- as an easier-to-conjugate alternative.
