When learning English, it’s not enough to know just the basic “yes” or “I agree.” To sound natural and fluent, you need idioms—those colorful expressions that native speakers use every day.
Idioms are short phrases with meanings different from the literal words. They add life, style, and personality to conversations.
When it comes to agreeing with someone, idioms play a big role. They help you express agreement in creative, polite, or even humorous ways.
Instead of repeating the same “me too” or “that’s right,” idioms allow you to fit smoothly into discussions, whether in casual chats with friends, classroom discussions, or professional meetings.
In this article, we’ll explore 40+ idioms for agreeing with someone, organized into useful groups. Each idiom comes with its meaning, example, similar expressions, and a note on where it’s often used. By the end, you’ll have plenty of natural phrases to use in daily conversations.
Did You Know?
The word “idiom” comes from the Greek word idiōma, meaning “a special feature” or “peculiarity.” That’s why idioms are unique ways of expressing ideas. Interestingly, many idioms for agreeing are rooted in history, music, and even old legal traditions—like “singing from the same hymn sheet,” which comes from church choirs needing to follow the same page to stay in harmony!
