ᴱ√PAẎA root. “requite, punish, take vengeance on, conquer, subdue”
A root in the Qenya Lexicon of the 1910s glossed “requite, punish, take vengeance on, conquer, subdue”, with derivatives like ᴱQ. paime “the vengeance taken, the punishment, the penalty; an infliction” and ᴱQ. paitya- “repay, requite” (QL/72), along with augmented forms like ᴱQ. apaika “conquering” and ᴱQ. apaire “victory, conquest, reduction” (QL/34). G. abair “victory” from the contemporaneous Gnomish Lexicon was almost certainly related (GL/17). The root ᴹ√SPAY “despise, contemn” from The Etymologies of the 1930s might also be related (Ety/SPAY).
Neo-Eldarin: For purposes of Neo-Eldarin, I think this root might be salvaged as ᴺ√PAY “punish, take vengeance on, requite” to serve as the basis for Neo-Quenya words for vengeance and punishment.
