Writing: Conventional expression — Example

- [Instructor] Interpol's Works of Art division confirmed that my great-grandmother's wedding ring and the ring stolen from the British royal treasury in 1918 are one in the same. All right, so this is interesting. They've underlined the word in. And this expression, one in the same, is sometimes something that you might hear, but it's actually the incorrect expression. The correct expression is one and the same. One and the same. And it's just an expression people use. It's kinda to be extra redundant, I guess you could say, 'cause to say that they are one and to say that they are the same, well, you're saying the same thing over and over, but it's kinda making their clear. They are one and the same. This is an expression. This is the conventional expression that you will hear people say. So this in should be and. And this one is a pretty hard one because of how often these two expressions are confused, one in the same and one and the same. People will hear someone say, "One and the same," or hear them say it really quickly, "One and the same," and then it sounds like they said, "One in the same." And then that person will repeat, "One in the same," and then a lot of other people think that the expression is one in the same. But one in the same, if you think about it, just doesn't make a lot of sense. It's like having one thing in the same thing. So just remember that that just, it's a little bit strange. The correct expression is one and the same. So we definitely don't wanna leave it the way it is. One and the same. One of the same, well, that's not the expression. And one over the same, that's not it for sure as well.
