falathren

proper name. Shore-language

In the drafts of the Lord of the Rings appendices, a Late Noldorin [Sindarin] name for the common tongue spoken along the shores of western Middle-earth that would eventually develop into Westron (PM/32). This name is most likely a combination of falas “shore” and the adjective suffix -ren, after undergoing the phonetic change: [[s|medial [s] became [θ] before [l], [r]]].

Conceptual Development: The word N. Falathren also appeared in The Etymologies from the 1930s, but there it was an adjective referring to the region or Elvish folk of the Falas (Ety/PHAL). Their dialect of Ilkorin was called Falathrin (LR/170), of which a few examples appeared: Fal. Ariad(or) (Ety/AR²) and Fal. galbreth (Ety/BERÉTH).
