A noun in The Etymologies of the 1930s given as {dravon or dravn >>} N. drafn “hewn log” derived from the root ᴹ√DARAM “beat, hew” (Ety/DARÁM; EtyAC/DARÁM). This word would be pronounced [dravn], and I prefer the less ambiguous spelling ᴺS. dravn for purposes of Neo-Sindarin; see the discussion of the Sindarin phoneme [v] for details.
