Sometimes, people don’t say “I am sick” in a plain way. They use fun or clever phrases instead. These phrases are called idioms. Idioms are special groups of words that mean something different than what the words usually mean. You might hear them at school, at home, or in shows. They make talking more colorful and interesting.
When someone is feeling bad or unwell, they might say, “I’m under the weather” or “I caught a bug.” These phrases don’t mean they are really under clouds or caught an insect. They are just other ways to say they are sick. Learning these can help you understand others better and make your own speaking more fun.

Reading passage
Last Friday, right before the school dance, Josh said he felt under the weather. He had a sore throat and looked pale as a ghost. Mrs. Carter, the school nurse, told him to rest because he might have caught a bug. His best friend, Leo, wasn’t doing so great either. He had a splitting headache and said he was feeling queasy after lunch.
At lunch, more kids were dropping like flies. Ms. Walker noticed and sent three students to the nurse’s office. One of them said, “I think I’m coming down with something too.” By afternoon, Emma was so wiped out, she couldn’t finish her project. She told her teacher, “I’m just not feeling myself today.”
By the time the dance started, half the class was either at home or laid up in the nurse’s room. The music still played, but it was a quieter night than anyone expected.
