nimpa

adjective. drooping, ailing

An adjective glossed “drooping, ailing” in notes probably from around 1959 based on the strengthened form of the root √(N)DIP “drooping” (PE17/168). For purposes of Neo-Quenya, I would assume this word applies to those who currently feel weak or ill but may or may not be actually sick.
