The word "sleep" originates from Old English "slǣp," which referred to the state of rest or slumber. It is derived from the Proto-Germanic *slēpaz, linked to the verb *slēpaną ("to sleep"). This root is shared across Germanic languages (e.g., Dutch "slaap," German "Schlaf"). The word has retained its core meaning of bodily rest with suspended consciousness throughout its evolution, reflecting its fundamental role in human life.
