Every Little Thing is Going to be Alright. Or All Right?

Did you know that there is a debate going on whether or not "alright" is a word. Grammarians argue that it is not--that it should always be "all right." But *I* have to argue with that. To me, "all right" means one thing, while "alright" means something different.
The distinction, in my mind, is slight, but there. I don't think I would say, "All right, let's get moving." But to me, "Alright, let's get moving!" is acceptable.

Merriam-Webster says that "all right" means:
all right
adjective
1. satisfactory, agreeable <Whatever you decide is all right with me.>
2. safe, well <He was sick, but he is all right now.>
3. good, pleasing --often used as a generalized term of approval. <He was an all right guy.>

So which definition would fit in the previous sentence? None of them, really. Unless you mean it is agreeable to get moving, but that just isn't what it means to me in that context. So then the next question is, what *does* it mean to me in that context? And my answer: I don't really know. Scary, huh? I've been using a word, that is not *really* a word and I don't really know how to define it either.

Upon further research, I found this at "The Free Dictionary."

Usage Note: Despite the appearance of the form alright in works of such well-known writers as Langston Hughes and James Joyce, the single word spelling has never been accepted as standard. This is peculiar, since similar fusions such as already and altogether have never raised any objections. The difference may lie in the fact that already and altogether became single words back in the Middle Ages, whereas alright has only been around for a little more than a century and was called out by language critics as a misspelling. Consequently, one who uses alright, especially in formal writing, runs the risk that readers may view it as an error or as the willful breaking of convention.

But M-W says that "alright" is gaining some acceptance. As does Mignon. But they also claim that it is not accepted yet.

Moral of the story? I guess it would be don't use "alright" because it isn't a word.
That makes me sad, somehow.
