olvar (sg. #olva) noun "growing things with roots in the earth, *plants" (Silm). Apparently more or less the same word as olwa, olba, which is however glossed "branch". Cf. laima.
Quenya
olva
noun. plant, growing things with roots in the earth
olvar
growing things with roots in the earth, *plants
tarmasundar
place name. Roots of the Pillar
A set of ridges extending from Meneltarma into each of the five regions (points of the “star”) of Númenor, translated “Roots of the Pillar” (UT/166). This name is a compound of tarma “pillar” and the plural form sundar, a variant sunda of sundo “base”.
sulca
root
sulca ("k") noun "root" (especially as edible) (SÚLUK)
tarma
noun. pillar
A word for “pillar” attested as an element in several words like Meneltarma “Pillar of Heaven” (SA/tar) and Tarmasundar “Roots of the Pillar” (UT/166). Christopher Tolkien suggested it was related to tar- “high” (SA/tar), but it could also be related to tar- “stand”.
Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. sūle “pillar, column” under the early root ᴱ√SULU (QL/87) and ᴱQ. taule “pillar” under the early root ᴱ√TAW̯A (QL/90). The word súle “column” also appeared in the Poetic and Mythological Words of Eldarissa (PME/87), while the plural form Tauler appeared in the Official Name List (PE13/104), both documents also from the 1910s.
sundo
base, root, root-word
sundo (þ) noun "base, root, root-word" (SUD), sc. a Quendian consonantal "base". According to VT46:16, Tolkien changed the root to STUD, thereby implying that sundo was earlier þundo (compare Sindarin thond "root"). PE18:95 gives the pl. form as sundur, seemingly implying a stem-form sundu-. It is not, however, used in the compound sundocarmë "base-structure" (PE18:84 not **sunducarmë), a term used in the description of the structure of the various Quendian "bases" or roots.
tarma
pillar
tarma noun "pillar" (SA:tar); Tarmasundar (þ) "the Roots of the Pillar", the slopes of Mt. Meneltarma in Númenor (UT:166)
numbë
root, foundation
[numbë noun "root, foundation", also núvë (VT45:38)]
núvë
root, foundation
[núvë noun "root, foundation", also numbë (VT45:38)]
sundo
noun. base
base
talma
base, foundation, root
talma noun "base, foundation, root" (TALAM), also translated "bottom" in the expression "top to bottom", see below.% Talmar Ambaren (place-name, *"Foundations of the World" - this is pre-classical "Qenya" with genitive in -en instead of -o as in LotR-style Quenya) (TALAM). Allative talmanna in the phrase telmello talmanna** "from hood to base**, top to bottom" _(VT46:18; notice misreading "telmanna" in the Etymologies as printed in LR, entry TEL-, TELU-)_
tulwë
pillar, standard, pole
tulwë noun "pillar, standard, pole" (LT1:270)
A word for plants appearing only in its plural form olvar “plants” (S/45; NM/270). It may be related to the roots √OLOB “branch” and √OL “grow”, hence “growing thing” as opposed to a celva = “moving thing” (WJ/341). For purposes of Neo-Quenya, I think this word refers mainly to plants as a category of beings (as in the Plant Kingdom), as opposed to an individual plant which would laima.
