G. telm or telum was glossed “roof; sky” in the Gnomish Lexicon of the 1910s, both derivatives of the root ᴱ√tel (GL/70). ᴱN. telum “sky” appeared again in Early Noldorin Word-lists of the 1920s (PE13/153), but by The Etymologies of the 1930s N. telu meant only “dome, high roof” (Ety/TEL), and its connection to “sky” seems to have been abandoned in Noldorin/Sindarin, though retained in Quenya telumë.
