A word in The Etymologies of the 1930s derived from the root ᴹ√DORON (Ety/DÓRON).
Conceptual Development: The Gnomish Lexicon of the 1910s had G. Dorna “ilex, holm oak” (GL/30), cognate of ᴱQ. norne “oak-tree” which was derived from the early root ᴱ√NOŘO [NDOÐO?] in the contemporaneous Qenya Lexicon (QL/67). The Gnomish word became dorn “oak” in Gnomish Lexicon Slips modifying that document (PE13/113). See ᴱN. gorw “oak” for other early “oak” words.
Neo-Sindarin: Tolkien introduced words S. norð and Q. nordo “oak” in notes from the late 1950s or early 1960s (PE17/25). I prefer the form Q. norno “oak” as better-established and more etymologically interesting. I would thus use [N.] doron “oak” for purposes of Neo-Sindarin, which make it easier for us to retain N. nordh “cord” as well (Ety/SNUR).
