An untranslated word appearing in notes on The Feanorian Alphabet from the late 1940s or early 1950s (PE23/26). It might be a later iteration of G. adhwen “approach, avenue” from the 1910s, or is perhaps related to S. adu and ᴹQ. atwa “double”.

A noun in The Etymologies of the 1930s glossed “muscle, sinew; vigour, physical strength” derived from primitive ᴹ✶tūgu under the root ᴹ√TUG (Ety/TUG). This root also had an adjective N. tong “taut, tight; resonant (of strings)”, clearly referring to the use of sinew in making stringed instruments. Thus I think tû likely refers mainly to “muscle, sinew”, and only metaphorically to “vigour, physical strength”, as in: i-Edhel han sâv dû “that Elf has muscle (tû) = has physical strength”.
Conceptual Development: Early Noldorin Word-lists of the 1920s had ᴱN. núr “muscle” from primitive ᴱ✶snóra (PE13/151).
