A noun appearing as N. rhomru “sound of horns” in The Etymologies of the 1930s, a combination of N. rhom “horn” and (archaic) N. †rhû “loud sound, trumpet-sound” (Ety/ROM).

Neo-Sindarin: Since the unvoicing of initial liquids did not occur in Sindarin, many people adapt this word as ᴺS. romru for purposes of Neo-Sindarin, as suggested in Hiswelókë’s Sindarin Dictionary (HSD).

Conceptual Development: The Gnomish Lexicon of the 1910s had G. ligindon “blare of trumps”, an elaboration of G. ligin “curved horn, trump” (GL/54).
