“It’s raining cats and dogs” makes no sense if you picture it literally, and that’s exactly why idioms trip kids up. An idiom definition for kids clicks fast once what is an example idiom sits right next to it. This list breaks down 65 common idioms by theme, each paired with a plain meaning and a sentence a child would actually hear.
What Is an Idiom?
An idiom is a group of words that means something different from what the individual words suggest. When someone says a task is “a piece of cake,” they aren’t talking about dessert, they mean the task is easy. Idioms develop over generations through storytelling, farming life, and everyday habits, which is why so many reference food, weather, or animals. For kids, they can feel like a secret language adults already know, and once a phrase like “break the ice” clicks, conversation gets a lot less confusing.
List of Idioms for Kids: Meanings and Examples by Theme
Below is a list of idiomatic expressions organized by theme. Each table pairs the idiom with a simple meaning and an example sentence a child can picture.
Idioms About Feelings and Emotions
Kids feel big emotions long before they have the words to explain them, and idioms give those feelings a shape. These phrases let a child describe nervousness, joy, or jealousy without having to explain the whole story behind it. Learning them also helps kids recognize the same feelings when a book character or classmate uses one.

Tips for Teaching Idioms to Kids
Idioms stick best when they connect to something a child has actually experienced.
- Point them out in real time: Pause on an idiom in a book or conversation and ask what the child thinks it means before explaining.
- Pair literal and figurative meanings: Sketching a literal “raining cats and dogs” scene next to the real meaning helps the idea stick.
- Practice one theme at a time: Working through a single category, like food or weather idioms, keeps the list from feeling overwhelming.
- Turn it into a game: Matching idioms to meanings on flashcards keeps the lesson playful instead of academic.
Idioms are one of those language quirks that seem baffling until the moment they click, and once they do, a child starts noticing them everywhere. This list of 65 idioms, spanning feelings, effort, friendship, school, time, nature, food, and everyday conversation, gives parents a practical starting point for building that recognition gradually and turning it into a shared joke along the way.
