A word glossed “wood” appearing in a list of “large & small” roots from around 1968 derived from primitive ✶tawĭnā (PE17/115) and hence probably an adjective “✱wooden, (made) of wood” as suggested by Helge Fauskanger (QQ/toina).
Conceptual Development: In The Etymologies of the 1930s Tolkien instead had ᴹQ. taurina “of wood”, an adjectival form of ᴹQ. tavar “wood (material)” (Ety/TÁWAR). The word ᴹQ. toina appeared in notes on The Feanorian Alphabet from the 1940s, but was unglossed, so whether it meant “✱wooden” is unclear.
