A noun in the Qenya Lexicon of the 1910s appearing as ᴱQ. turu and described as “properly = firewood — but used of wood in general as a material”, a derivative from the root ᴱ√TUŘU [TUÐU] (QL/96). It also appeared in the contemporaneous Poetic and Mythological Words of Eldarissa with the gloss “wood (material)” (PME/96) and appeared again as turu “wood” in Early Qenya Word-lists of the 1920s (PE16/139). It appeared once more many years later as an element in the name Turuphanto “Wooden-whale” (UT/191), and so may remain viable in Tolkien’s later conception of the language.
Neo-Quenya: For purposes of Neo-Quenya, I think it is preferable to use the word Q. töa for “wood (material)”.
