Ilk. Ariador loc. “Land Outside”
A variant form of Argador “[Land] Outside the Fence”, marked as Falathrin in The Etymologies (Ety/GAT(H), Ety/AR²). If so, it is evidence that in that dialect, primitive [g] became [i] between an [r] and a vowel, just as in the main Ilkorin dialect [g] became [i] between an [l] and a vowel.
Conceptual Development: In the Gnomish Lexicon from the 1910s, ᴱIlk. Aryador or Ariador was also said to be a dialectical word, from (early) Ilkorin (GL/20), possibly with a similar phonetic development.
