The prefix Hypno- denotes which state?

• A. Light
• B. Sleep
• C. Dream
• D. Wakefulness

Answer: (B)

Hypno- denotes sleep. It comes from the Greek hypnos, the personification of sleep, and appears in terms like hypnosis, hypnotic, and hypnotherapy to signal a sleep-related state or effect. You can see it in hypnagogic, which describes the transition into sleep. While sleep can involve dreaming, the word for dream uses a different root (oneiro-), so hypno- specifically flags the sleep state itself rather than light, wakefulness, or dreaming.
