An unglossed root in the Outline of Phonology from the early 1950s illustrating certain phonetic combinations (PE19/98), and therefore possibly not a “real” root.
Primitive elvish
sak
root. draw, pull
lemek
root. [unglossed]
phut
root. [unglossed]
An unglossed root appearing in the second version of Tengwesta Qenderinwa (TQ2) as an etymological variation of √PUT (PE18/90).
sal
root. [unglossed], *harp(ing), lyre
The unglossed root ᴱ√SALA appeared in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. salma “lyre, small harp” and ᴱQ. salumbe “harping, music” (QL/81). The root √SAL appeared again Common Eldarin: Verb Structure from the early 1950s to illustrate the reformed perfect form of its verb Q. asálie (PE22/132), but since these later forms are unglossed it is unclear whether they have the same meaning (“✱harp(ing)”) as the earlier version of the root.
stuk
root. [unglossed]
tig
root. [unglossed]
A root appearing in Late Notes on Verb Structure (LVS) from 1969 as the basis for the verb Q. tinga- “go (for a long while)” (PE22/157). The etymology was marked with an “X” and so was probably a transient idea (PE22/157 note #70).
graw Reconstructed
root. [unglossed], [ᴹ√] dark, swart
This root appeared as a primitive form grawa serving as the basis of the word Q. roa “bear” >> “dog” in notes on monosyllabic roots from 1968 (VT47/35); a Sindarin derivative S. graw “bear” appeared in other notes written around the same time (VT47/12). Patrick Wynne suggested that in the sense “bear” grawa might be connected to the root ᴹ√GRAWA “dark, swart” from The Etymologies of the 1930s (EtyAC/GRAWA).
The root ᴱ√SAKA first appeared in the Qenya Lexicon of the 1910s with derivatives having to do with “search” (QL/81). The root ᴹ√SAK also appeared in The Etymologies from the 1930s with no gloss or derivatives (EtyAC/SAK). However, as pointed out by Lokyt in a Discord chat on 2019-07-26, the words ᴹQ. sak- “to be hurt” from Quendian & Common Eldarin Verbal Structure (EVS1) of the 1940s and Q. sahta “marred” (< ✶saknā?) from notes written in the late 1950s (MR/405) might be related.
The root appeared as √SAK “draw, pull” in notes associated with Quenya prayers from the 1950s as part of an alternate derivation of Q. úsahtië “inducement to do wrong, ✱temptation” (VT43/23); elsewhere this word was given as a derivative of √THAG “press” (VT43/22). The Sindarin cognate úthaes (VT44/30) is hard to explain as a derivative of √SAK, so it is likely that this was only a transient idea, especially since Tolkien indicates that the older form of the verb sahta- “to induce” was †þahta- (VT43/23).
Neo-Eldarin: For Neo-Eldarin writing, it is probably better to ignore the 1950s form of this root and assume its derivatives are from √THAG. For the senses “draw” and “pull” I mostly recommend using the roots √LUK or ᴹ√TUK instead, though I do accepted Hialmr’s neologism ᴺS. thag- “draw, pull”; see that entry for discussion. In place of ᴱ√SAKA “✱search”, it is probably better to use derivatives of √KETH “examine, ✱seek”. This leaves ᴹ√SAK to be the basis of “hurt, mar” words.
