A word appearing as ᴱQ. tantara “bouncing, resilient” in the Qenya Lexicon of the 1910s, an adjectival form of the verb ᴱQ. tanta- “bounce, bound, rebound” (QL/93-94). Early Qenya Word-lists of the 1920s instead had tanta “bouncing, resilient” (PE16/142).
Neo-Quenya: Since I retain ᴺQ. tanta- “to bounce, bound, rebound” for purposes of Neo-Quenya, I would retain ᴺQ. tantara “bouncing, resilient” as well.
A verb appearing as ᴱQ. rakta- “stretch out, reach (intr.)” in the Qenya Lexicon of the 1910s under the early root ᴱ√RAHA “stretch forward” (QL/78).
Neo-Quenya: A later iteration of this root is ᴹ√RAK “stretch out, reach” from The Etymologies of the 1930s, so I think this verb can be retained as ᴺQ. rahta- “to stretch out, reach”, slightly modified to fit later Quenya phonology. Helge Fauskanger used such a modified verb in his NQNT (NQNT).
