When you're closing a door, you're moving it from open to shut. But closing also means the end of something, like the closing minutes of a basketball game or the closing scene of a movie.

In business, a closing is the final meeting where a deal becomes official. When a family buys a house, they attend a closing where they sign papers and receive the keys. Real estate agents talk about “closing the deal,” meaning they've successfully completed a sale. Salespeople also use closing to describe the moment when they convince someone to buy something: the point when a maybe becomes a yes.

Closing can describe the act of shutting down permanently. When a store is closing, it's going out of business for good. You might see a “Store Closing Sale” sign in the window.

The word also appears in a closing argument, which is the final speech a lawyer makes in a trial, summarizing everything before the jury decides. It's their last chance to persuade, which is why it carries special weight.

Notice how closing often marks the transition from one state to another: from open to shut, from selling to sold, from trying to convince to actually convincing, from operating to finished. These final moments matter because they determine the outcome of everything that came before.
