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.
