What is the difference of all right and alright in usage?
It has always been true that the form alright has been more common in non-formal contexts. But it has also been used for the better part of the century by undoubtedly notable writers. Theodore Dreiser used it through the manuscript for The “Genius”, though H.L. Mencken made him change it to all right. Other alright users include James Joyce in Ulysses, Flannery O’Connor, Mordecai Richler, Langston Hughes, and Gertrude Stein. While in general, alright can be found in all the senses of all right, in practice there can be a real semantic distinction between the two, because the two word form all right can mean ‘all correct’ or something like that, while alright can only mean ‘good; safe; healthy’, etc. when used as an adjective.
