A word as appearing as ᴱN. taglon “smith” in Early Noldorin Word-lists of the 1920s (PE13/153), where it was element in ᴱN. Barthaglon or Balthagron “World Smith” (PE13/138). The Gnomish Lexicon of the 1910s had archaic G. †tagor along with modern G. tagros or taglos “smith” (GL/68), elements in G. Martaglos or Maltagros “Smith of the World” (GL/56). These word were likely based on the early root ᴱ√TAKA “fix, fasten” (QL/88).
Neo-Sindarin: In Tolkien’s later writings, the name “World-artificer” became Barthan where the second element was based on ᴹ√TAN “make, fashion” (Ety/TAN; LT1A/Talka Marda). However, I think the earlier words can be salvaged as ᴺS. tagron “smith” for purposes of Neo-Sindarin.
A word for “footstep” in Nebrachar poem written around 1930, appearing only in its plural form methail “footsteps” (MC/217). Its second element is probably related to tal “foot” having undergone nasal mutation. The basis for its initial element (man- or men-?) is unclear, but it could be related to ᴹ√MEN from the 1930s.
