Why this word is great

SOMNOLENT — [Adjective] Inclined to or suggestive of drowsiness. From the Latin somnus ("sleep"), via Old French sompnolent and French somnolent. Unlike "lethargic," which implies a general, leaden inertia of spirit, or "soporific," which names an active, external cause of sleep, "somnolent" describes the quiet, internal state of surrender. It is the heavy-lidded gaze of a cat in a sunbeam, the slow, syrupy blink that fails to reopen, and the muffled, rhythmic sound of a train in a distant valley at night—the body's quiet surrender to gravity and its oldest wisdom, where waking life softens at the edges into the arms of oblivion.
