orto

oro
mount, mountain
oro (1) noun "mount, mountain" (PE17:64), cf. Qenya oro noun "hill" (LT1:256; rather ambo in LotR-style Quenya, though #oro "mountain, hill" appears in Orocarni and orofarnë, q.v. [PE17:83], also with the meaning "high" in oromar, q.v.) Cf. oro- element "up, aloft" (PE17:64).
oro
noun. mount, mountain, hill
An element meaning “mountain” or “hill” given as a derivative of √ORO/RŌ (PE17/64, 83) and appearing in various Quenya compounds in the 1950s and 60s: Q. Orocarni “Red Mountains” (MR/77), Q. Orofarnë “Mountain Ash” (PE17/83), Q. oromandi “mountain dweller[s]” (PE16/96), and Q. Pelóri “Mountain Wall” (PE17/26). It also appeared as ᴱQ. oro “hill” in the Qenya Lexicon of the 1910s as a derivative of the early root ᴱ√ORO (QL/70).
See the discussion in the entry for Q. oron “mountain” for more details on the conceptual developments of this and related words.

raise
A word meaning “mount, mountain” given as a derivative of √ORO/RŌ in Notes on Galadriel’s Song (NGS) from the late 1950s or early 1960s (PE17/64). In The Etymologies of the 1930s, ᴹQ. orto “mountain-top” appeared as a derivative of the root ᴹ√OROT (Ety/ÓROT).
Neo-Quenya: For purposes of Neo-Quenya, I think it is best to use orto with its 1930s sense “mountain-top”, and use Q. oron for “mountain”; see that entry for more details on the conceptual developments of this and related words.
