Introduction
“Fluency grows when useful language moves from the page into your voice.”
Idioms are phrases whose meanings cannot always be understood from the individual words. They appear in everyday conversations, films, workplace discussions, sport, and social media.
This book focuses on expressions you are likely to hear and use in real life. Each card gives you a clear meaning, a concise origin note, natural examples, and guidance on when the expression fits.
How to use this book
- Study five to ten idioms at a time.
- Say both examples aloud and create one example of your own.
- Use the quick quizzes for active recall instead of rereading.
- Notice register and context before using an idiom.
- Return to difficult cards until the expression feels natural.
