Idioms are short phrases that don’t always mean exactly what the words say. They are used in stories, conversations, and even in cartoons or books. For example, if someone says, “It’s raining cats and dogs,” they don’t mean animals are falling from the sky. It just means it’s raining very hard. Idioms help make language more interesting and fun to use.
This article will help you learn a few simple idioms that are good for beginners. You will also get to practice using them by rewriting basic sentences. These idioms are easy to understand and use in daily life. Learning them step by step can help you feel more confident when reading or speaking.
