Key Phrases: What to Say When You Don't Understand
Sometimes in English, you hear a word you don't know. Sometimes someone speaks too fast. Sometimes you miss part of a sentence. This happens to everyone—even native English speakers! The good news is that there are simple phrases you can use to ask for help. These phrases keep the conversation going so you can get the information you need.
Here are the four most useful things you can ask when you don't understand:
Ask for the meaning of a word
Ask someone to repeat
Ask someone to speak slowly
Check that you understood correctly
Say thank you and confirm
How It Works: A Simple Step-by-Step
When you don't understand something, follow these simple steps. Both you and the other person work together to fix the problem. This is normal in every conversation!
This is a team effort. You ask for help, and the other person helps you. Then you both continue the conversation. It is not an interruption—it is how good communication works!
Visual Explanation: The Repair Cycle
The diagram below shows what happens step by step when you ask for help in a conversation. Look at how the conversation moves from the problem all the way to understanding!
Both people work together to fix the problem. Your job is to ask a clear question. The other person's job is to explain or repeat. When you say "I understand," you both know you can keep talking. This is a normal, helpful part of every conversation.
Four Types of Clarification Phrases
There are four main reasons you might not understand. Each reason has its own phrases. Match the right phrase to the right problem!
Type 1: Ask for Repetition
Use this when you didn't hear the words clearly—maybe the person spoke too quietly or there was noise. Try: "Can you repeat that?" or "Could you say that again, please?" or "Sorry, I didn't catch that." The very short "What?" or "Huh?" is okay with close friends, but it can sound rude in class, at work, or with people you don't know well. Use the longer phrases in those situations.
Type 2: Ask for the Meaning of a Word
Use this when you heard a word clearly but you don't know what it means. The best phrase is: "What does ___ mean?" Put the word in the blank. For example: "What does 'deadline' mean?" You can also say "I don't understand the word ___." This is a great way to learn new words while you are speaking!
Type 3: Check That You Understood
Use this when you think you understood, but you want to make sure. Say what you think the person means and ask if you are right. Try: "Do you mean ___?" or "So you're saying ___?" or "You mean ___, right?" The other person will say "yes" if you are right, or explain more if you are not.
Type 4: Ask Someone to Speak More Slowly
Use this when the person is speaking too fast for you to follow. Say: "Can you speak more slowly, please?" You can also say "Can you spell that for me?" when you hear a word but can't understand how it sounds. These phrases are very helpful at school, at the doctor's office, or at work.
Formality & Register: Choosing the Right Phrase
In English, some phrases are more polite than others. You use different phrases with different people. For example, the way you talk to a friend is different from the way you talk to a teacher or a doctor. The table below shows three levels: casual (with friends), neutral (for most situations), and formal (for a job interview, a doctor, or a teacher).
| Type | Casual (friends) | Neutral (most situations) | Formal (teacher, doctor, interview) |
|---|---|---|---|
| Repetition | What? / Huh? | Can you repeat that? | I'm sorry, could you repeat that, please? |
| Meaning | What's that mean? | What does ___ mean? | Could you explain what ___ means? |
| Confirmation | You mean ___? | Do you mean ___? | If I understand correctly, you're saying ___? |
| Slower speech | Slow down! | Can you speak more slowly? | Would you mind speaking a bit more slowly, please? |
| Spelling | How do you spell that? | Can you spell that for me? | Would you mind spelling that, please? |
Worked Example: Navigating a Real Conversation
Let's look at a full conversation. A beginner English learner is at a university office. Watch how the learner uses different phrases to understand what the office worker is saying.
Strengths, Pitfalls, & Cultural Considerations
These phrases are very helpful, but it is good to know when to use them and when to be careful. The table below shows what is good about these phrases and what problems can happen.
| Strengths | Things to Watch Out For |
|---|---|
| Keep you in the conversation instead of pretending to understand and losing even more information. | Overusing "What?" or "Huh?" without naming the word you don't understand can be confusing and slow things down. |
| Help you learn new words by asking about them when you hear them. | In some cultures, asking for clarification may feel uncomfortable. But in English-speaking places, it is normal and polite. |
| Show the other person that you are listening and trying to understand—this often makes them more patient and helpful. | Asking many questions at once in a busy group conversation can be hard. Try to ask one question at a time. |
| Give you confidence because you know what to say when you don't understand. | Try to also practice listening every day so you need these phrases less and less over time. |
As Your English Gets Better
The phrases you are learning now are the first step. As your English improves, you will learn longer and more detailed ways to ask the same questions. The table below shows how the same ideas look at beginner, intermediate, and advanced levels.
| Type | Beginner (A1–A2) | Intermediate (B1–B2) | Advanced (C1–C2) |
|---|---|---|---|
| Asking what a word means | "What does ___ mean?" | "I'm not sure I follow—could you explain what you mean by ___?" | "I'd like to unpack that term a bit—are you using ___ in the technical sense, or more colloquially?" |
| Checking understanding | "Do you mean ___?" | "So, if I'm understanding correctly, you're suggesting that ___?" | "Let me paraphrase to make sure we're aligned: your position is that ___, correct?" |
| Saying you don't understand | "I don't understand." | "I'm afraid I've lost the thread—could you go back to the point about ___?" | "That's a complex point. Could you walk me through the reasoning step by step?" |
You can see that the question is always the same—you always want to understand better. What changes is how you say it. Right now, short and clear phrases are best. As you practice more English, you will add longer and more detailed phrases. Every phrase you learn now is a strong first step.

Lesson Summary
This lesson taught you clarification and repair phrases—simple phrases that help you stay in a conversation when you don't understand something. You learned four types of phrases: ask for repetition, ask for the meaning of a word, check your understanding, and ask someone to speak slowly. You also saw how these phrases work step by step in a real conversation, shown in the repair cycle diagram.
You learned that some phrases are casual (for friends), some are neutral (for most situations), and some are formal (for teachers, doctors, and job interviews). The worked example showed a real conversation where a student used three different phrases to understand a university office worker. Remember: these phrases are not a sign of weakness—they are a sign of a smart, active learner who wants to understand and keep learning in every conversation.
