Under the weather
English Idiom
Meaning: Feeling unwell or sick, often due to a minor illness like a cold or flu. It can also refer to feeling out of sorts or generally not in top form.
Origin: The phrase 'under the weather' originates from maritime slang. When sailors were feeling ill, they were sent below deck to protect them from the harsh weather conditions. Over time, this expression evolved to describe anyone who is feeling unwell.
