There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

place name. the Sea

rôs

noun. endurance, meekness, patience, gentleness

rôs

noun. embrace

rôn

noun. embrace, clasp

A noun appearing as G. rôn or rôs “embrace” in the Gnomish Lexicon of the 1910s, related to the verb G. rôtha- “embrace” (GL/66). On another page rôn⁽⁾ “clasp, embrace” was marked archaic and tied to (likewise archaic) G. râ “arm” (GL/65). Perhaps this word became archaic due to clashes with G. rôn “liver”.

Neo-Sindarin: I adapt the related Gnomish verb G. rôtha- as ᴺS. ranga- (see that entry for discuss), so I would revise its noun form to ᴺS. rangoth as a combination of that verb with the suffix -th.
