limpa adj. "frail, slender and drooping" (PE17:168)

limpa

adjective. frail, slender and drooping

An adjective glossed “frail, slender and drooping” in notes probably from around 1959 based on the unstrengthened form of the root √(N)DIP “drooping” (PE17/168). For purposes of Neo-Quenya, I would assume this word applies to things that are physically frail, originally in the sense of such things being unable to support themselves upright due to thinness.
