An unglossed root in the Qenya Lexicon of the 1910s with variant ᴱ√TUKU⁽²⁾ and derivatives like ᴱQ. tuksa “gross, 144” and ᴱQ. tuksa pínea or tuksa lempea “100”, the variation in meaning likely due to the use of the word in duodecimal vs. decimal counting (QL/95). In the Early Qenya Grammar of the 1920s, ᴱQ. tuksa was used only with the sense “100” (PE14/49, 83). This is the last clear reference to an Elvish word for “100”, so I recommend keeping a Neo-Root ᴺ√TUKSA for this purposes, though Q. haranyë “century” (LotR/1108) hints that Tolkien may have used some of other construction for “100” in his later writings.
