Ok, perhaps I should just calm down, but I have heard more and more people using "upped" as a verb. Even in newspaper stories!

Now, I don't know about you, but I always thought that prices were "raised" not "upped". Up is a preposition, not a verb. Prices can go up, they can follow an upward trend, they rise, but they do not "up".

I looked on m-w.com and they do have an entry for up as a verb, but I still think it is wrong and should be struck from the English language.

Let's take this sentence and play with it a little: "The builder upped the price for the house." Very much like something you have heard before. Now let's change one word. "The builder upped the walls for the house." Sounds stupid doesn't it. You don't "up" walls, you raise them. Well, you don't "up" prices either.
