The forms √SLIT and √LIT appear in a rejected page of roots from the 1948 Quenya Verbal System (QVS) with some unclear glosses, probably “swiftly, speed”; they were the basis for the past-tense form lhinte “sped” of otherwise unattested verb ᴹQ. lhit- (PE22/127). This root might be connected to later Q. linta “swift” from the Namárië poem (LotR/377; PE17/63), though elsewhere Tolkien indicated that Q. linta (< ✱lim-tā?) was the equivalent of S. lim “quick, swift” (PE17/147).

yen
root. year
A root in The Etymologies of the 1930s glossed “year” with derivatives like ᴹQ. yén/N. în “year” (Ety/YEN). Tolkien’s ongoing use of words like Q. yén and S. ínias “annals” indicate its ongoing validity (LotR/377; MR/200), but in Quenya at least the meaning shifted to that of an “Elvish long year”, equal to 144 solar years (LotR/1107; MR/471; NM/84).

angwa
root. snake
The root √ANGWA “snake” with variant √ANGU appeared in The Etymologies of the 1930s as the basis for the words ᴹQ. ango “snake” (Ety/ANGWA) and angulóke “dragon” (Ety/LOK). The Noldorin equivalent am- seems to have survived only as a prefix (Ety/ANGWA), and is a good example of how [[on|[ŋgw] > [mb]]] in that language. There are a variety of other words for “snake” in Tolkien’s later writings, so whether this root remained valid is unclear.

root. swallow
A root in The Etymologies of the 1930s glossed “swallow” with variant ᴹ√LANK and derivatives ᴹQ. lanko/N. lhanc “throat” (Ety/LAK¹, LANK), the latter an element in N. tarlanc “stiff-necked, obstinate” (Ety/TÁRAG). This last word was changed to S. tarlang in Tolkien’s later writings (PE17/92; RC/536), consistent with an earlier but rejected form ᴹ√LANG for ᴹ√LANK in The Etymologies (Ety/LANK).
In later writings, Q. lango/S. lang meant “neck” rather than “throat”, so it is tempting to retain ᴹ√LAK for “throat” and other swallow-words. But it would be very confusing to have such similar but unrelated words for “neck” and “throat”, so I recommend using the root ᴹ√SLUK for “swallow” instead, and Q. lango, S. lang for both “neck” and “throat”.

srō
root. east
A root appearing in a rejected page of roots from the Quenya Verbal System (QVS) written in 1948 (PE22/127), possibly as a variant of √RŌ/ORO that Tolkien introduced to explain S. rhûn “east” after he decided initial r- did not become rh- in Noldorin/Sindarin; see the entry on S. rhûn for discussion.

ṇdūnē
noun. sunset
An unglossed root in The Etymologies of the 1930s with derivatives ᴹQ. litse/N. lith “sand” (Ety/LIT). Elsewhere N. lith was translated “ash” (TI/208), so perhaps the meaning of the root was something like “✱(fine) grit”. Tolkien’s continued use of S. lith “ash” indicates its ongoing validity (RC/765; SA/lith).
