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.

poli
noun. meal
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

tata

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).
This Elvish root was connected to the sense “two” or “both” throughout Tolkien’s life. The first clear manifestation of this root was ᴱQ. yú “twice” and ᴱQ. yúyo “two” from the Early Qenya Grammar of the 1920s (PE14/49-51, 82-84). The root ᴹ√YŪ “two, both” appeared in The Etymologies of the 1930s with derivatives like ᴹQ. yúyo “both” and ᴹQ. yúkale/N. uial “twilight” (Ety/KAL, YŪ). The root √YU appeared several times in Tolkien’s later writings, generally with the sense “both” (PE17/70; PE21/74; VT48/8, 10). It was likely related to the ancient dual suffix ✶-ū.
