schlaff

German

Etymology

From Middle High German slaf, from Old High German slaf, from Proto-Germanic *slap-, perhaps ultimately from Proto-Indo-European *(s)leh₂b- (to be weak, limp, languid), see also Latin labō (fluctuate, waver).[1]

The same word of Low German origin is schlapp, a synonym in modern standard German.
