herfst m (uncountable)
From Old Dutch *hervist, from Proto-Germanic *harbistaz, from Proto-Indo-European *kerp-. Cognate with High German Herbst, Low German Harvst, West Frisian hjerst, English harvest; further with Latin carpere (“to pick, to pluck”), Greek καρπός (karpós, “fruit, harvest”). The original meaning was ‘harvest time’, as is seen in herfstmaand.
