A word loosely translated as “moon” in the Markirya poem of the 1960s (MC/222), but more accurately “moonlight” according to the glossary following the poem (MC/223), perhaps an elaboration of Q. silmë “starlight” under the influence of Q. Isil “moon”.
Conceptual Development: A similar word ᴱQ. silma “a ray of moonlight” appeared in the Qenya Lexicon of the 1910s, derived from the early root ᴱ√SILI which was also the basis for ᴱQ. Sil “moon” (QL/83).
isilmë (þ) noun "moonlight", occurring in Markirya; free translation "the moon" in MC:215 (isilmë ilcalassë, literally "moonlight gleaming-in" = "in the moon gleaming"). Isilmë also appears as the name of a Númenorean woman (UT:210).
