Polite Ways to Say ‘I am not sure’
When you are unsure about something, saying “I am not sure” can sound blunt or dismissive in both casual and professional settings. The direct phrase often leaves the listener feeling that you are uninterested or unwilling to help. Polite alternatives allow you to express uncertainty while showing respect, willingness to find an answer, or careful consideration. This guide gives you practical, ready-to-use phrases for everyday conversation, workplace talk, and professional emails.
Quick Answer: What to Say Instead of ‘I am not sure’
If you need a polite replacement right now, use one of these phrases depending on your situation:
- For casual conversation: “I’m not entirely sure, but I think…”
- For workplace speaking: “Let me check on that for you.”
- For professional emails: “I would need to confirm before giving a definite answer.”
- For formal situations: “I am not in a position to say with certainty.”
Each of these softens the uncertainty and shows you are engaged in the conversation.
Understanding the Problem with ‘I am not sure’
The phrase “I am not sure” is grammatically correct and widely used. However, it can sound negative or final. When you say it without any softening, the other person may think you are avoiding responsibility or that you do not care. In English-speaking cultures, especially in workplace and professional contexts, it is better to show that you are still thinking, willing to help, or need more time. The polite alternatives below help you do exactly that.
Polite Alternatives for Everyday Conversation
In casual settings with friends, family, or acquaintances, you can use these phrases to express uncertainty without sounding rude or distant.
1. “I’m not entirely sure, but I think…”
This phrase adds a small hesitation before your opinion. It shows you are being honest about your doubt while still offering your best guess.
Example: “I’m not entirely sure, but I think the meeting is at 3 PM.”
2. “I couldn’t say for certain.”
This is a gentle way to admit you do not know. It sounds humble and avoids sounding like you are making excuses.
Example: “I couldn’t say for certain whether she will come.”
3. “I’m not 100% sure, but my guess is…”
This phrase is very common in friendly conversation. It signals that you are guessing and that the other person should not rely on your answer completely.
Example: “I’m not 100% sure, but my guess is the restaurant opens at noon.”
4. “I’d have to double-check.”
This shows you are willing to find the correct answer. It is polite and proactive.
Example: “I’d have to double-check the time. Let me look it up.”
Polite Alternatives for Workplace Speaking
In meetings, one-on-one conversations, or team discussions, you need phrases that show competence and cooperation. These alternatives work well in spoken workplace English.
1. “Let me check on that for you.”
This is one of the most professional and helpful phrases. It turns uncertainty into action.
Example: “I’m not sure about the deadline. Let me check on that for you.”
2. “I don’t have that information at hand, but I can find out.”
This phrase is honest and shows you are resourceful. It avoids making excuses.
Example: “I don’t have that information at hand, but I can find out and get back to you.”
3. “I’d like to confirm before I say yes.”
Use this when you need to verify facts before committing. It shows responsibility.
Example: “I’d like to confirm before I say yes. Can I get back to you in an hour?”
4. “That’s a good question. Let me think about it.”
This phrase buys you time and shows respect for the question. It is especially useful in meetings.
Example: “That’s a good question. Let me think about it for a moment.”
Polite Alternatives for Professional Emails
In written communication, you cannot rely on tone of voice. Your words must carry the politeness. These phrases work well in email subject lines and body text.
1. “I would need to confirm before giving a definite answer.”
This is formal and clear. It shows you are careful and accurate.
Example: “Regarding your request, I would need to confirm before giving a definite answer. I will update you by tomorrow.”
2. “I am not in a position to say with certainty at this moment.”
Use this for very formal or sensitive situations. It is respectful and avoids overpromising.
Example: “I am not in a position to say with certainty at this moment. I will consult with the team.”
3. “I will look into this and get back to you.”
This is a standard professional phrase. It is direct, polite, and action-oriented.
Example: “Thank you for your question. I will look into this and get back to you shortly.”
4. “I am not entirely sure, but I will find out.”
This combines honesty with a promise to help. It is suitable for semi-formal emails.
Example: “I am not entirely sure, but I will find out and let you know.”

Natural Examples in Context
Here are full sentences showing how these phrases sound in real life.
- Friend asks about a movie time: “I’m not entirely sure, but I think the show starts at 7:30. Let me check the app.”
- Colleague asks about a project deadline: “Let me check on that for you. I know it’s this week, but I want to confirm the exact date.”
- Client email about pricing: “I would need to confirm before giving a definite answer. I will send you the updated quote by end of day.”
- Boss asks for an opinion in a meeting: “That’s a good question. Let me think about it for a moment.”
Common Mistakes to Avoid
Even with polite phrases, learners sometimes make small errors. Here are the most common ones.
- Mistake 1: Using “I am not sure” without any follow-up. This sounds like you are ending the conversation. Always add what you will do next, like “but I can find out.”
- Mistake 2: Over-apologizing. Saying “I’m sorry, I’m not sure” too often can make you seem less confident. Use a polite phrase instead of an apology.
- Mistake 3: Using the same phrase for every situation. “Let me check on that” is great for work, but too formal for friends. Match the phrase to the context.
- Mistake 4: Forgetting to follow up. If you say “I will get back to you,” make sure you actually do. Otherwise, you lose trust.
Better Alternatives for Specific Situations
Sometimes you need a phrase that fits a very specific context. Here are targeted alternatives.
When you are unsure about facts
Use: “I don’t have the exact figure, but I can look it up.”
When you are unsure about someone’s feelings
Use: “I can’t say for sure how they feel, but I think they might be open to it.”
When you are unsure about a plan
Use: “The plan is still tentative. I will confirm once I know more.”
When you are unsure in a formal meeting
Use: “I would need to review the data before I can give a definitive answer.”
