文化的背景

This phrase is a hallmark of the 'linear' logic preferred in Western academia. It reflects the Socratic method of building a series of undeniable truths to reach a final conclusion. Using it correctly marks you as someone trained in professional or academic English.

💡

The Comma is Key

Always put a comma after the phrase. It gives your reader a tiny 'breath' to prepare for the big logical leap you're about to make.

Don't 'Extend' Too Far

Make sure the two points are actually related. If the connection is too weak, you'll sound like you're trying too hard to be smart.

What It Means

Think of a telescope. You see one star clearly. Now, you pull the telescope out further. You see a whole galaxy. Extending this argument does exactly that. You take a proven point. You apply it to a larger context. It shows your brain is working hard. It connects two ideas with a logical bridge.

How To Use It

Place it at the start of a sentence. Always follow it with a comma. It acts as a transition. It tells the reader to stay focused. You are not starting a new topic. You are just growing the current one. It is like adding a trailer to a truck. You are carrying more weight with the same engine.

When To Use It

Use it in your university essays. It works wonders in business proposals too. Use it when you want to look logical. It is perfect for serious debates. If you want to win an argument, use this. It makes your logic feel unstoppable. It belongs in the boardroom or the lecture hall.

When NOT To Use It

Avoid this during a first date. It sounds a bit robotic there. Don't use it for simple facts. 'The sky is blue. Extending this argument, I like blue.' That sounds silly. Keep it for complex ideas. Your friends might roll their eyes if you are too formal. It is not for ordering coffee.

Cultural Background

Western culture loves 'step-by-step' thinking. We like to see how Point A leads to Point B. This phrase comes from legal and academic history. It is about building a 'case.' It shows you value reason over emotion. It is a very 'Ivy League' way to speak. It signals that you are an intellectual.

Common Variations

You can say building on this. Or try furthering this logic. By extension is a shorter version. Taking this a step further is more common in speech. All of these keep the momentum going. They keep your audience on the hook. They show you have a deep plan for your talk.

使い方のコツ

This is a high-register transition. Use it when you want to demonstrate rigorous thinking, but avoid it in casual settings to prevent sounding pretentious.

The 'Smart' Signal
