ᴱ√MAÞA root. “dusk”
This root was given as ᴱ√MASA¹ “dusk” in its main entry in the Qenya Lexicon of the 1910s, but its Gnomish form math- indicates the true root was ᴱ√MAÞA (QL/59). This was clarified in a list of roots at the end of the M-section in the Qenya Lexicon (QL/63) and its representation as maþ- in the contemporaneous Gnomish Lexicon (GL/59). Its most notable use in the Legendarium was in the name G. Umboth-muilin “Pools (muil-plural) of Twilight (umboth)”, where G. umboth or umbath “nightfall” was derived from a strengthened form of the root, ᴱ√mbaþ- (GL/75). However, in later writings this name was reconceived as Ilk. Umboth Muilin “Veiled (muilin) Pool (umboth)”, with the first element umboth meaning “large pool” (Ety/MBOTH, MUY). The name was ultimately replaced with S. Aelin-uial (S/114), by which point the early root ᴱ√MAÞA was long abandoned.
