An onomatopoeic root with variants ᴹ√TING and ᴹ√TANG appearing in The Etymologies of the 1930s with derivatives ᴹQ. tinge or tango “twang”, ᴹQ. tinga- “to twang”, and N. tang “bowstring” (Ety/TING). The entry had a reference to a deleted variant ᴹ√THING (EtyAC/TING) and another variant ᴹ√TUNG was listed in the entry ᴹ√DING (EtyAC/DING). In the Quenya Verbal System of the 1940s Tolkien gave the root ᴹ√TAÑ as the basis for the verb ᴹQ. tanga- “twang”, which is probably another instance of this root (PE22/103).

root. hump
A root in The Etymologies of the 1930s glossed “hump”, with Quenya and Noldorin derivatives of the same meaning (Ety/TUMPU). It might be a later iteration of the root ᴱ√KUPU “hump” from the Qenya Lexicon of the 1910s which had derivatives like ᴱQ. kumpo “pile” and ᴱG. cub “hollow” (QL/49; GL/27). Alternately, it could be a later interation of ᴱ√TUMU “swell (with idea of hollowness)” (gloss marked with “?”) from the same document, but the one clear derivative of ᴱ√TUMU was ᴱQ. tumbe “trumpet, large horn” (QL/95), which seems unrelated to 1930s ᴹ√TUMPU.

Túna (Ety/TUN), which continued to appear in later writings as the name of a hill (S/59). The word ᴹQ. lopotundo “rabbithole” from the Declension of Nouns of the early 1930s indicates the root may have had a difference sense (“hole”?) in earlier writings (PE21/10, 31).
