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).
Quenya
oro
noun. mount, mountain, hill
oro
mount, mountain
oro
(high) above
orto
noun. mount, mountain, hill, [ᴹQ.] mountain-top; [Q.] mount, mountain
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.
oromar
noun. lofty hall, high-mansion, high (lofty) dwelling
A word appearing in its plural form oromardi, referring to the dwelling of Varda and Manwë on the slopes of mount Taniquetil from the Namárië poem (LotR/377). It is a combination of oro- “up, aloft” and mar(da) “dwelling” (PE17/63-64). Though not a proper name, I suspect this word was poetic and not in general use.
oro-
prefix. up, aloft
oro-
verb. rise
oro- (2) vb. "rise" (LT1:256; Tolkien's later Quenya has orta-, but cf. oro #1)
lissë miruvóreva mí oromardi
of sweet nectar in the high-halls
The 4th phrase of the prose Namárië. Tolkien altered the text from the poetic version as follows:
> mi oromardi lissë miruvóreva >> lissë miruvóreva mí oromardi
Tolkien moved the possessive element lissë miruvóreva “of sweet nectar” forward in the prose version so that it immediately follows the noun it modifies, namely the lintë yuldar “swift draughts” of the previous line. Thus “swift draughts of sweet mead” as in the English translation of the poem.
orta-
verb. to rise
Tolkien defined an intransitive verb orta- “to rise” based on the root √OR “rise”, first mentioned in The Etymologies of the 1930s where Tolkien had ᴹQ. orta- glossed both transitive “raise” and intransitive “rise” (Ety/ORO). This intransitive verb reappeared in the Quenya Verbal System (QVS) of 1948 as ta-formative ort(a), contrasted with ta-causative ᴹQ. ortā́ “raise, lift” = “✱make rise” (PE22/114). In this paradigm, intransitive “rise” was distinguished from transitive “raise” mainly in its half-strong past tense oronte “rose” (or archaic †ronte), as opposed weak past ortane “raised, lifted” (PE22/115).
In QVS, Tolkien gave another intransitive verb ᴹQ. orya-, and said “to avoid the confusion with the causatives -ya was preferred for intransitives: so oryane, rose, ortane, raised” (PE22/115). This seems to indicate orya- “rise” was preferred. Despite this, intransitive orta- “rise” continued to appear in Tolkien later writings (PE17/52, 64; PE21/77; PE22/164) as an alternate to orya- “rise”, which appeared regularly as well (see that entry for details).
Conceptual Development: For purposes of Neo-Quenya, I prefer the more distinctive verb orya- for “rise”, and I use orta- only for transitive “raise”. However, some Neo-Quenya writers like the idea of a transitive/intransitive verb distinguished by different past forms. For example Helge Fauskanger used orta- for both “rise” and “raise” in his NQNT (NQNT).
orta-
verb. rise
orta- vb. "rise", also transitive "raise, lift up", pa.t. ortanë (Nam, RGEO:67, ORO; misreading "ortani" in Letters:426). According to PE17:63-64, this pa.t. form ortanë is only transitive ("raised"), whereas the intransitive pa.t. ("rose") is orontë. Cf. orya-.
orya-
verb. to rise
An intransitive verb for “to rise” mentioned in various places in Tolkien’s later writings of the 1940s, 50s and 60s, based on the root √OR “rise” (PE17/64; PE22/114, 156). Tolkien usually described it as a ya-formative verb with a half-strong past oronye (PE17/64, 77; PE22/164), though Tolkien occasionally gave it a weak past oryane (PE22/115, 157).
Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. oro- “rise” based on the early root ᴱ√ORO (QL/70). In a rejected page of verbs and roots from the Quenya Verbal System (QVS) written in 1948, Tolkien had [verb?] ᴹQ. oro, orro “up, rise (from ground)” derived from the root ᴹ√SRŌ (PE22/127), but in the main document he used ya-formative ᴹQ. orya- for “rise” (PE22/114-115), possibly the first appearance of this version of the verb. Tolkien sometimes gave the intransitive Quenya verb for “to rise” as ta-formative orta- with half-strong past oronte; see that entry for discussion.
Neo-Quenya: For purposes of Neo-Quenya, I prefer orya- “rise” with half-strong past oronye, and because Tolkien said “-ya was preferred for intransitives” (PE22/115).
orya-
verb. rise
orya- vb. "rise" (intrasitive only, contrast orta-), pa.t. oronyë (PE17:64)
Túna
hill, mound
Túna (also Tún) place-name, used of the hill on which Tirion was built (Silm, TUN, KOR), derived from a stem (TUN) apparently meaning simply *"hill, mound".
ambo
hill, rising ground
ambo noun "hill, rising ground" (Markirya, PE17:92), "mount" (PE17:157), allative pl. ambonnar "upon hills" in Markirya (ruxal' ambonnar "upon crumbling hills") According to VT45:5, ambo was added to the Etymologies as a marginal note.
ambona
noun. hill
amun
hill
amun (amund-) noun "hill" (LT2:335; in Tolkien's later Quenya ambo)
orta/orya
verb. rise
tundo
hill, mound
tundo noun "hill, mound" (TUN)
umbo
hill, lump, clump, mass
umbo, umbon noun "hill, lump, clump, mass" (PE17:93)
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.
