morion

masculine name. the Dark One

Another name for Melko in the poem Fíriel’s Song from the 1930s (LR/72), possibly a combination of the stem form mori- of more “dark” and some variation of the agental suffix -ndo.

Conceptual Development: This name also appeared in the Qenya Lexicon from the 1910s, where it was glossed “Son of the Dark” (QL/62), a combination of the root ᴱ√MORO “dark” and some form of yondo “male descendant”.

morionde

place name. Morionde
