Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!



noun. twilight, shadow, vagueness

A Doriathrin noun meaning “twilight, shadow, vagueness” derived from root ᴹ√MUY (Ety/MUY). Its Quenya cognate ᴹQ. muile suggests a primitive form of ✱✶muı̯lē [mujlē].

Conceptual Development: Tolkien seems to have coined this word to explain Umboth Muilin “Twilight Meres”, a remnant of earlier G. Umboth-muilin “Pools of Twilight”. The meaning of the Ilkorin elements is reversed from the earlier name: in the Gnomish name muilin “pools” was the plural form of the word G. muil, glossed “tarn” in the Gnomish Lexicon (GL/58) which is an older English word for “(mountain) lake”. In later writings, Tolkien replaced this name with S. Aelin-uial “Meres of Twilight”.
