means A powerful opioid drug derived from opium, used medically to relieve severe pain and notorious for its high potential for addiction.

from Coined in the early 19th century by a German pharmacist who isolated the active compound from opium and named it after Morpheus, the Greek god of dreams and sleep — a nod to the drowsy, dreamlike stupor it induces. The name traces back to Greek 'morphe,' meaning 'form' or 'shape,' since Morpheus was the dream-spirit who took human shapes to appear in sleepers' visions.
