morë is a word meaning "dark" or "darkness" in Quenya and perhaps Telerin.
It is seen as mori- in compounds (see etymology below).
Etymology
Primitive mori (the short final i becoming e in Common Eldarin stage) root MOR.
From primitive mori, the i remains so in compounds: morequendi is wrong because *morikwendî > moriquendi.
