I couldn't find the exact best place for this, but here we go: Interpsed apparently does not exist as a word, and yet, word 2007 marks it as correct. If you look it up using the dictionary function, it does not come up. If you look it up online at dictionary.com or other such resources, it does not come up. If you google it, you can find several examples of its usage in various writings, but no definition. I understand it to be a synonym for the word " interposed, " basically meaning placed in between things. The examples i found agree with my definition, more or less. So what is the deal? Is this the word that the internet forgot?
