How to Pronounce Hypersomnia

Hypersomnia is pronounced hy-per-SOM-nee-ah. The stress falls on the third syllable, which rhymes with "mom." Say it like you're saying "higher" (hy-per) followed by "SOM" (rhyming with "mom"), then finish with "nee-ah."

The stressed syllable is SOM, which is the third syllable out of four. A common mistake is stressing the first syllable (HY-per-somnia) instead of the third, so remember to put the emphasis on the middle part of the word.

Hypersomnia breaks into four syllables: hy-per-SOM-nee-ah. Each syllable is roughly one beat when you say the word slowly.

Hypersomnia comes from two Greek roots: "hyper" means "over" or "excessive," and "somnia" relates to sleep. Put together, hypersomnia literally means "excessive sleep" or "too much sleep."

Hypersomnia is the medical word for sleeping way more than usual or feeling extremely sleepy during the day when you should be awake. Think of it as your body's sleep switch being stuck in the "on" position.

Yes! Insomnia (in-SOM-nee-ah) is the opposite — it means not being able to sleep. Both words share the "somnia" root, but "hyper" means too much and "in" means not enough.

Hypersomnia is sometimes shortened to "hypersomnolence," but there isn't a single standard two- or three-letter abbreviation like you see with some other medical terms. You'll usually see the full word or the longer form used in medical writing.

You might hear: "The patient reported experiencing hypersomnia, sleeping 12 hours a night and still feeling tired during the day." This sentence shows how the word is used to describe a specific sleep-related experience.
