A noun appearing as N. thafn “post, wooden pillar” in The Etymologies of the 1930s derived from ON. sthamne < ᴹ✶stabnē under the root ᴹ√STAB having to do with wooden things (Ety/STAB). Here the f in thafn was almost certainly pronounced “v” in keeping with Noldorin spelling conventions.
Neo-Sindarin: For purposes of Neo-Sindarin I would update this word to ᴺS. thavn to better fit Sindarin spelling conventions; the pronunciation of the word wouldn’t change. I would use this word only for a wooden pillar or post, which was probably more common in Sindarin construction. For a stone pillar I would use [ᴺS.] gonnoth.
Conceptual Development: Earlier pillar words include G. talpon “a slender pillar” based on G. talp “prop or support” (GL/69) and G. taul {“burden” >>} “a pillar” related to G. tul- “†to support” (GL/69), both from the Gnomish Lexicon of the 1910s.
