This entry is one in a series that tackles issues of proper word use and grammar in English.
This choice has always bothered me because ‘alright’ has seemed too clipped and too vernacular. According to Merriam-Webster, either form is fine, though ‘all right’ is older. I’m going to stick with the longer, two word form. If that makes me a traditionalist, so be it. Random House has an interesting discussion of when you can interchange the two forms and when they mean different things.
