I blame Pete Townsend and legions of subliterates who have been “misunderedumacated” in “gummint” schools (A.K.A. “prisons for kids”) for the disgusting spread of “alright” in place of the useful and perfectly good “all right.” Yeh, yeh, so James Joyce wrote “alright” ONCE, as against dozens of uses of “all right.” Big deal. Even if Joyce’s usage had been flipped the other way, he wrote Suckitudinous Fiction that only appeals to sophomoric idiots who feign intellectual pursuits. (Yes, I am completely serious in that assertion.)
Heck, eve with Pete Townsend’s endorsement for the stupid, “alright” only gained any traction at all with the advent of massive “democratic” stupidity inflicted on English by “mass-man” (see Ortega) via the Internet. And even with the promulgation of subliterate stupidity via subliterate writing, editing, and self-publishing, one can be thankful the use of “all right” still VASTLY outweighs the deplorable infliction of “alright” on the English language.
So, if you insist on being a Philistine, a nekulturny subliterate (A.K.A. “trailer trash,” etc.), go ahead and use “alright” in private emails where you might be safe doing so, or in a public form where you can be raucously mocked. No skin off my nose either way. But if you (assuming a reader who wants to be a published writer and expects to be paid for wordsmithery) want to avoid a raucous mocking in, say, an Amazon review, get it right, mmmK?
