A word appearing as an element in the name Lisgardh “Land of Reeds” (UT/34).
Conceptual Development: An earlier version of this name was G. Arlisgion or Garlisgion “Place of Reeds” (LT2/153; GL/67), which contained G. lisg or lisc “reed, sedge” from the Gnomish Lexicon of the 1910s (GL/54). This became ᴱN. lhesg “sedge” in Early Noldorin Word-lists of the 1920s (PE13/148).

Middle Primitive Elvish
sed
root. rest
esek
root. *sedge, reed
A (Ilkorin-only?) root in The Etymologies of the 1930s with the derivatives Ilk. esg “sedge, reed”, Ilk. esgar “reed-bed”, and Ilk. Esgaroth “reed-lake” (Ety/ESEK). Elsewhere it seems S. lisg means “reed” as in S. Lisgardh “Land of Reeds” (UT/34), and similarly ᴹQ. liske < ᴹ✶lisge (PE19/51). Thus I suspect ᴹ√ESEK was a transient idea, one of the etymologies Tolkien considered for Esgaroth.
ezdē
noun. rest
lisge
noun. reed
Doriathrin
esg
noun. sedge, reed
A noun meaning “sedge” derived from the root ᴹ√ESEK (Ety/ESEK), probably from a primitive form ✱✶eseke. The middle [e] was lost due to the Ilkorin syncope, and afterwards the [[ilk|[esk] became [esg]]], as suggested by Helge Fauskanger (AL-Ilkorin/esg).
êd
feminine name. Rest
Early Quenya
liske
noun. sedge, reeds
fen
noun. reed
kaitoile
noun. rest
A noun appearing as kaitȯile “rest” in the Qenya Lexicon of the 1910s, apparently derived from (deleted) ᴱQ. kaito- “lie quiet” (QL/46). The significance of the marked ȯ is not clear.
Early Noldorin
lhesg
noun. sedge
Qenya
liske
noun. reed, reed, [ᴱQ.] sedge
A word mentioned in the Outline of Phonetic Development (OP1) of the 1940s, with the gloss “reed” and derived from primitive ᴹ✶lisge (PE19/51).
Conceptual Development: The word/root ᴱQ. LISKE “sedge, reeds” appeared in the Qenya Lexicon of the 1910s (QL/55). In the contemporaneous Name-list to the Fall of Gondolin, [ᴱQ.] liske was given as a cognate to G. lisg “reed” (PE15/28).

erde
feminine name. Rest
This root first appeared as ᴹ√SED “rest” in The Etymologies of the 1930s with derivatives like ᴹQ. sére “rest, repose, peace” and N. sîdh “peace”, along with the name of the Valië ᴹQ. Este < ᴹ✶ezdē (Ety/SED). The root √SED “rest” along with the etymology of Este reappeared in both the Outline of Phonetic Development (OP1) from the 1940s (PE19/45) and the Outline of Phonology (OP2) from the early 1950s (PE19/92), and again in revisions to the OP2 page annotated in green ink and thus probably from 1970 (PE19/91 and note #110).
The root √SED “rest” was mentioned a couple times in the Quenya Verbal System (QVS) from 1948 as the basis for the verb ᴹQ. ser- “rest, repose” (PE22/102, 125) and again (unglossed) in the Quendi and Eldar essay of 1959-60 as the basis for Este (WJ/403). In the sense “peace” this root had some competition, however. In the first version of the Gloria in Excelsis Deo prayer from the mid-1960s, Tolkien used Q. sívë for “peace”, revised to Q. sérë in the second version and then Q. rainë (VT44/32). The word Q. sívë “peace” reappeared in unpublished etymological notes from 1969 derived from the root √SIB “rest, quiet” (VT44/35).
Neo-Eldarin: For purposes of Neo-Eldarin, I would use √SED for the act of resting and so Q. sérë “peace” = “restfulness (personal peace)”, and would use √SIB = “quiet, ✱stillness, absence of activity” and so Q. sívë “peace” = “absence of activity or violence (environmental peace)”. I would use Q. rainë as “good will” in connection to √RAY “smile”.
