A Lot more than just one. I mess with my kids' minds using homophones and homynyms. One of my favorites is pair, pear, and pare. I say to them, "I'm hungry. Can you pare a pair of pears for me?"

Reading some of the posts on the forums is sort of like reading a teenager's text message on their cellphone ( R U goin 2nite?) It may shorten things, but it makes little sense most of the time. I'm an old-schooler, and I think spelling, and proper grammar, is a reflection on 1- your education, and 2- your personal "precision".

And another phrase that gets jammed into one word is all right. Already is one word, but all right is two.
