Etymology: Apomorphine is a chemical built by modifying morphine, the opium alkaloid named after Morpheus, the Greek god of dreams. The "apo-" prefix comes from the Greek "apó," meaning "away from" or "off," and in chemistry it usually signals a compound derived from another by removing water, so apomorphine is morphine altered by a chemical reaction rather than a separate plant product. The name of morphine itself traces to Morpheus, the god who shaped dreams in Ovid's account, because its sedative effects seemed to induce sleep. The Greek ending "-eus" in the god's name gave way in the English form to "-ine," the standard suffix for alkaloids, which reflects the Latin "-inus" that passed through French before reaching English. Apomorphine's modern uses rest on its action on dopamine receptors, which explains why a molecule derived from an opium compound is now prescribed for Parkinson's disease and related conditions.
