英語で丁寧に反対・断る方法｜ビジネスでも使える自然な表現と例文集
In English communication - especially in business - knowing how to disagree politely or refuse requests is an essential skill.
Simply saying no or disagreeing too directly can sound rude or unfriendly, even if you don’t mean it that way.
By learning polite English expressions for refusal and disagreement, you can communicate clearly, build good relationships, and sound more natural and professional in conversations.
1. Why Soft Language Matters
In some cultures, being direct is considered honest.
But in English (especially British English) direct disagreement can sound too strong.
Instead, we usually soften our language to show respect for the other person’s ideas (even if the ideas are bad!).
2. Direct vs. Polite Disagreement
A direct disagreement can sound too harsh:
✘ I disagree. (Sounds blunt and unfriendly.)
✔ I’m not sure I agree with that. (Softer and more polite.)
✔ I see your point, but I think there’s another way to look at it. (Shows respect before giving a different opinion.)
These softer phrases are common in meetings, negotiations, and discussions. They make your English sound professional and cooperative.
3. Useful Phrases for Disagreeing Politely
Here are some useful phrases you can use depending on the situation:
Soft disagreement:
I see what you mean, but…
I’m afraid I don’t quite agree.
That’s an interesting idea, though I have a different opinion.
Partial agreement (common in British English):
I agree to some extent, but…
That’s true in some cases, however…
I understand your point, but we may need to consider another option.
Business-style disagreement:
I appreciate your suggestion, but I think we should explore other possibilities.
That’s a valid point, but the data suggests a different approach might work better.
These phrases sound polite, show that you’re listening, and still allow you to express a different view.
4. How to Refuse Politely
Sometimes you need to say no to an offer, invitation, or request.
Saying just “No” is grammatically correct, but it often sounds rude.
Use these polite alternatives (bold words make it polite)
Everyday polite refusals:
I’d love to, but I’m afraid I can’t.
Thank you, but that’s not possible for me right now.
That sounds great, but I already have other plans.
Business polite refusals:
I appreciate the offer, but we’ll have to decline at this time.
Thank you for your proposal, but it’s not the right fit for our current strategy.
That’s a useful idea, but we don’t have the budget for it at the moment.
These phrases allow you to refuse clearly while still sounding respectful and professional.
They balance a ‘thank you’ with a reason for refusal.
5. Cultural Notes: British vs. American Style
British English:
British speakers often use indirect language to avoid sounding too strong.
Words like perhaps, a bit, I’m afraid, and phrases like I see what you mean, but… are common.
I’m afraid I don’t quite agree. (Very polite, soft)
That’s a bit difficult for us right now. (Understatement, common in business English)
This indirectness shows politeness and is highly valued in professional and social situations.
American English:
American speakers are usually more direct but still polite.
They might say I don’t agree with that or I think there’s a better solution without many softening phrases.
I don’t agree with that approach. (Polite but more straightforward)
I think we should try something else. (Clear and direct)
In a business context:
American English often values clarity and efficiency.
British English prioritises politeness and tone.
6. Practice
Choose the most polite option in each situation.

A. I don’t think that will work.
B. I see what you mean, but I have a different idea.
C. That’s completely wrong.

B. That’s an interesting idea, though I’m not sure it’s the best solution.
C. That’s not going to happen.
Conclusion
Disagreeing and refusing are normal parts of communication, but how you do it matters.
Polite language helps you express your opinion clearly while maintaining good relationships, especially in business.
Using soft phrases like I’m afraid I don’t quite agree or I’d love to, but I can’t will make your English sound natural, professional, and respectful.
