Etymology: "Hypersomniacs" is the plural of "hypersomniac," a noun for a person who suffers from hypersomnia, a condition of excessive sleepiness or sleeping for unusually long periods. The word is built from three familiar parts: the Greek prefix "hyper-," meaning "over" or "beyond," the Latin-derived "somnus," meaning "sleep," and the suffix "-iac," which marks a person affected by something. Hypersomnia itself is the medical term, and the personal noun simply follows the same pattern, as with "insomniac" for someone who cannot sleep.

Synonyms: sleepyheads, slumberers, dreamers, sleepers, drowsers
