A Sindarin name of Oromë translated “Lord of Forests” (S/29) or more literally “Forester” (PM/358), sometimes expanded to Aran Tauron “King Forester” (PM/358). This name is a compound of taur “forest” (SA/taur) and the masculine suffix -on.
Conceptual Development: In the Gnomish Lexicon from the 1910s, this name was G. Tavros glossed “the Blue Spirit of the Woods” (GL/69). In a late change to the Lays of Beleriand the name was changed to N. Tauros (LB/195) which was the form used in Silmarillion drafts from the 1930s (LR/206). In The Etymologies, this name was derived from a combination of taur “forest” and the lenited form of gost “terror” (Ety/GOS, TÁWAR). The name was revised to Tauron in Silmarillion revisions from the 1950s-60s (MR/202).
A neologism for “forester” created by Boris Shapiro in PPQ (PPQ) from the early 2000s, equivalent to S. Tauron. I think it is preferable to use the now-attested word Q. ornendur, published in 2021.
