The common Quenya word for “forest”, derived from the root √TAW “wood” (PE17/115; VT39/7).
Conceptual Development: In the Qenya Lexicon Tolkien had ᴱQ. tauno “great forest” derived from the root ᴱ√TAVA “beam” (QL/90). It seems to have had the form taur- in the early name ᴱQ. Rúsitaurion “Son of the Weary Forest” (LT2/89), and the form was ᴱQ. taure in the Oilima Markirya and its various drafts (MC/213, 220; PE16/62 ff.). In Qenya Word-lists of the 1920s it briefly had the form taurie (PE16/138). In The Etymologies of the 1930s it had the form ᴹQ. taure “great wood, forest” as a derivative of the root ᴹ√TAWAR of similar meaning (Ety/TÁWAR). It was mentioned regularly in Tolkien’s later writings, generally with the gloss “forest”.
taurë noun "(great) wood, forest" (SA:taur, Letters:308, TÁWAR. VT39:7), pl. tauri in Markirya
