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.

root. suppose
A root Tolkien introduced in the late 1960s with the gloss “suppose”, appearing beside √KE “maybe” (PE22/158). It also had an extended (verbal) form √KWIS “inquire, suppose” in this same document. This late root may have been a restoration of much earlier ᴱ√IQI “request, ask for” from the Qenya Lexicon of the 1910s, whose derivatives had to do with requests and requirements (QL/43).
The roots √KWI and √KE were in competition in the late 1960s as the basis for “if” words in hypthotheticals; see the entry on √KE/EKE for these alternatives.
Neo-Eldarin: For purposes of Neo-Eldarin I think it is best to use √KWI for “if” and √KE for “maybe”; I also think √KWI(S) “inquire” can be used to justify the restoration of some of the derivatives of early ᴱ√IQI, via a hypothetical Neo-Eldarin root ᴺ√IKWI(S) “request, ask for”.
phut

An unglossed root appearing in the second version of Tengwesta Qenderinwa (TQ2) as an etymological variation of √PUT (PE18/90).

pronoun. that
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).
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.
