What It Means

This phrase is like the ultimate 'mic drop' for facts. It tells your reader or listener that what comes next is a solid, proven truth. You aren't just sharing a personal opinion or a guess. You are stating something that has been backed by evidence or universal agreement. Think of it as the 'final boss' of factual statements in English.

How To Use It

You usually put this right at the start of a sentence. Follow it with the word that and then your big, undeniable fact. For example, It is indisputable that the Earth is round. It is a simple structure but carries a lot of weight. Don't use it for small things like your favorite pizza topping.

When To Use It

Use this when you are writing a serious paper for school or university. It is also great for business reports or formal speeches. If you have data or proof to back you up, this phrase is your best friend. It makes you sound very smart, confident, and authoritative. It is perfect for setting the foundation of a big argument.

When NOT To Use It

Avoid this when talking to your friends about movies, music, or food. If you say It is indisputable that this burger is good, you will sound like a robot. It is far too heavy for a casual chat over coffee. Also, never use it if the fact is actually debatable. If you use it wrongly, people will think you are being arrogant or closed-minded.

Cultural Background

English speakers value logic and evidence in formal debates. This phrase comes from legal and scientific traditions where 'disputing' something is a formal process. By saying it is indisputable, you are saying the debate is already over. It reflects a culture that prizes strong, assertive claims in professional settings.

Common Variations

You might hear people say There is no denying that. Another common one is It is undeniably true that. In more casual settings, people just say Obviously or Clearly. But for the big, serious moments in writing, stick to It is indisputable that to show you mean business.

Notes d'usage

This is a C1-level expression primarily used in academic and professional writing. It carries a high level of formality and should be followed by a factual statement rather than a purely subjective opinion.

Use it sparingly

If you use this phrase too often in one essay, you'll sound repetitive and aggressive. Save it for your strongest point!

⚠️

💬

The Sarcasm Secret

Native speakers sometimes use this very formal phrase for tiny, silly things to be funny. Like saying 'It is indisputable that I need a nap' after working for only ten minutes.
