A noun for “fall” appearing as an element of the title Noldolantë “Fall of the Noldor” (S/87).

Neo-Quenya: The word lasse-lanta “leaf-fall” (LotR/1107) indicates the noun for “a fall” should be lanta, which is also how the noun appears in The Etymologies of the 1930s (Ety/DAT). However, there is an alternate form lassewinta “leaf fall” in drafts of the Lord of the Rings appendices (PM/376) where the second element seems to be the infinitive of the verb winta-, so perhaps lasselanta also includes the infinitive of the verb lanta- “to fall”.

The form lantë more strongly resembles other Quenya nouns, which more often end in -e rather than -a. As such, I prefer lantë over lanta as the independent noun for “a fall”.
