reason

We use "reason" in several common ways. It can mean the power to think clearly and reach a sensible answer. It can also mean the why behind something, the explanation for an event or action. If you ask, "What's the reason for this?" you want to know the cause or purpose.

Think about building with blocks. The reason you stack them a certain way is to keep the tower steady. If it falls, you try to find the reason it failed so you can fix it. A good reason gives support to what you say or do. Sometimes it simply means a clear cause or explanation: "Lack of funding was the reason for the project's cancellation."

"Reason" is a surprisingly versatile word, operating as both a mental faculty and an explanation for events. At its core, reason is the power of thinking clearly and logically—the ability to form judgments based on facts and evidence rather than emotion or instinct. When someone says, "Use your reason!" they are urging you to think things through carefully.

But "reason" isn't just about how we think; it also describes why things happen. It can refer to the cause or justification for an action, belief, or event. For example: "The reason she was late was the heavy traffic," or, "There is no reason to be afraid."

As a noun, "reason" can also mean a statement offered in explanation or justification: "He gave several reasons why he couldn't attend the meeting." As a verb, it means to think logically and form conclusions: "The detective reasoned that the suspect must have had an accomplice."

You will often encounter the adjective "reasonable," meaning fair, sensible, or moderate. A reasonable request is one that isn't excessive or demanding. Conversely, you might hear about someone being "beyond reason," meaning they are acting irrationally or uncontrollably. Whether it's the mental process of thinking things through, the explanation for why something happened, or a justification for an action, "reason" is fundamental to understanding the world around us and making informed decisions.
