A noun appearing in the Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s as ᴱQ. lilt “a dance” based on the early root ᴱ√LḶTḶ (QL/55), where [[eq|short syllabic [ḷ] became [il]]] (PE12/11). In the English-Qenya Dictionary of the 1920s, the noun form was lalta, probably with [[eq|long syllabic [ḹ] becoming [al]]] (PE15/71).
Neo-Quenya: I would adapt this noun as ᴺQ. liltë “dance”, based on the later root ᴹ√LILT “dance” (Ety/LILT).
