Conceptual Development: In Lord of the Rings drafts from the 1940s, this name first appeared as (singular) N. Rath a Chalardain >> (plural) Rath a Chelerdain (WR/388). This form seems to included the genitive preposition N. an “of”, elided and causing nasal-mutation of the following noun, as suggested by Roman Rausch (EE/3.25).
