A root in The Etymologies of the 1930s glossed “height, mountain” given as an extension of ᴹ√ORO “up, rise, high”, with derivatives like ᴹQ. oron (oront-) “mountain” and N. orod “mountain” (Ety/ÓROT). The latter dates all the way back to G. orod “mountain” from the Gnomish Lexicon of the 1910s (GL/63), and continued to be used in later writings as S. orod as well (e.g. on LotR/469). The derivatives of the root on the Qenya side were more variable, sometimes given as Q. orto (PE17/64) or orot- (VT47/28) instead.
