What It Means

Think of this phrase as a bridge. On one side, you have a fact. On the other side, you have a conclusion. This proves that is the path between them. It tells your listener that your point is now a fact. It is not just a guess anymore. You are showing them the 'why' behind your 'what.' It is a very powerful way to speak. It turns a simple observation into a strong argument.

How To Use It

First, state your evidence clearly. Maybe you show a graph. Maybe you mention a specific event. Then, use the phrase This proves that. Finally, state your main point. For example, 'The car is wet. This proves that it rained.' It is simple and direct. You can also use it at the end of a long story. It helps wrap everything up into one neat package. You are essentially saying, 'Here is the smoking gun.'

When To Use It

This is perfect for the office. Use it during a big presentation. It makes you look like you know your stuff. You can also use it in daily life. Use it when you finally find your lost keys in the fridge. 'This proves that I need more sleep!' It works well in debates too. If you have a strong argument, this is your best tool. It is great for moments when you want to be persuasive.

When NOT To Use It

Be careful with this one. Do not use it if you are not 100% sure. If you say This proves that and you are wrong, you lose trust. It can sound a bit bossy if you use it too much. In a sensitive talk, try This suggests that instead. It sounds a bit softer and more polite. Avoid it when talking about purely subjective things like art or food. You cannot 'prove' that pizza is better than tacos.

Cultural Background

In many English-speaking cultures, logic is king. We love to see the evidence. We want to know the 'bottom line.' This phrase fits perfectly into that mindset. It started in science and law. Now, it is everywhere from TikTok to the boardroom. It represents a culture that values results and hard facts. It is the language of someone who has done their homework.

Common Variations

If you want to sound fancy, use This demonstrates that. If you want to be a bit more relaxed, try This shows that. In a scientific setting, you might hear This confirms that. If you are just chatting, This means that is a safe bet. Each one has a slightly different 'flavor' but the goal is the same. They all point to a conclusion based on what just happened.

Notes d'usage

This phrase is neutral in formality and fits almost any context. Be aware that it requires a full clause (subject + verb) after the word 'that'.

Softening the Blow
