O que significa "to put it in a nutshell"?

Do you know what a nutshell is? If you have never heard of that word before, just take a look at the picture above. That's what a nutshell is. Simple huh? But now you may be wondering what that has to do with the expression of the day. Well, technically nothing. An expression doesn't have to be necessarily attached to the literal meaning of its words. That's actually one of the main characteristics of an expression/idiom. But let's learn the expression with the word nutshell!

You know those moments when you want to be as straightforward as possible with someone? Maybe you're in a very complicated situation where you have to say something really embarrassing to someone. You want it to be really quick, so you make sure you use as fewer words as possible. For example, you're the boss at a very important company and now you have to lead a meeting with several of your employees to fire them. So, in the middle of the meeting, while you're trying to finally get to your point, you say: To put it in a nutshell, you're all fired.

In a nutshell means very briefly, something you say when you want to be very concise. So maybe during that meeting, you would have to go through all the explanations as to why your company needs to make many employees redundant. So to make things faster and easier [at least for you], you put it all in a nutshell and get it over with. The idea behind the expression is that a nutshell is very tiny and therefore it would hold a very small amount of anything. So imagine that when you use that expression, you're using a very small amount of words so it will fit in a nutshell. That's it for now guys. Take care!
