VOA慢速英语2021--词汇掌故：昙花一现

（单词翻译）

And now, Words and Their Stories, from VOA Learning English.

On this program we take a closer look at common words and expressions in the English language.

Today we will talk about how to describe something that shows promise of being great, but then turns out to be...not so great.

We can call this a flash in the pan.

First, let's look at the words in this expression. A flash is a sudden burst of light or fire -- here one second and gone the next. And a pan is a kind of container usually used for cooking. But it has other meanings, too. We will talk about that later.

Sometimes we use the expression "flash in the pan" for things that seem to be going well. There is hope! But then, in the blink of an eye, things turn bad. In other words, things go from good to bad very quickly.

An artist or entertainer could be described as a flash in the pan if their success happens quickly but does not last long. If a singer is a flash in the pan, we could also call him or her a one-hit-wonder. This expression describes an artist who has only one popular, or hit, song and then disappears from the spotlight¹.

Here is another example of how to use flash in the pan:

I thought that my new boss was going to be here for a long time. But she was just a flash in the pan. Here today, gone tomorrow.

Word experts say "flash in the pan" probably comes from an old kind of firearm called a musket². These weapons were used during the 16th to 17th century. But to understand the origin of this expression, we have to understand how a musket fired.

Experts on the website Revolutionary War Journal explain that firing a musket was complex. It took about 10 steps to fire these guns. So, the firing of a musket gun is very much a chain reaction – one action leads to another, and another, and another.

The muskets³ had a place for the gunpowder⁴ called a "pan." When you pulled the trigger, a piece of flint would hit a piece of steel called a frizzen. This would cause sparks to fly into the pan – also called a flash pan. This would light the gunpowder, which would then light the main charge. This, would, finally, fire the gun.

Sometimes.

Other times things went wrong in this chain reaction. For example, sometimes the charge in the pan would light but would fail to light the main charge.

The result?

The gun would not fire. When this misfire happened, people called it a "flash in the pan."

And misfires were common. Through time, the expression "flash in the pan" soon became used to describe other things.

But not VOA Learning English. It has been around for many years. So, it is not a flash in the pan. And we plan to be around for many more years to come!
