Acronyms I-P

What’s an acronym? It’s an abbreviation of a larger word (or words) that sometimes makes a new word on it’s own, such as DOS-Disk Operating System. I have accumulated a list of acronyms from various sources I have long since forgotten. If you know of some that are missing (I’m sure there are many), e-mail them to me and I’ll consider including them on the page.
