Under the weather
Meaning
To feel unwell or slightly sick.
Origin
Imagine a sailing ship battling a fierce gale in the 19th century. When a sailor became too ill—whether from seasickness or a fever—to stand watch on deck, they were sent below. This wasn't just for comfort; it was to protect them from the relentless wind, rain, and waves lashing the exposed deck, literally keeping them "under the weather" to recover. Often, they would be placed beneath the 'weather bow', the side of the ship taking the brunt of the elements, seeking refuge from the storm's fury. This practical nautical term for sickness eventually sailed ashore, becoming a universal metaphor for feeling unwell.
Examples
- I woke up feeling a bit under the weather this morning, so I think I'll stay home from work.
- She’s been under the weather all week with a nasty cold, but she’s starting to feel better now.
