All right as a word has multiple meanings:
E. g. Her dance was all right.
E. g. They get along all right
E. g. All right! I will do it for you.
E. g. Are you all right?
The form alright is a one - word spelling of the phrase all right. Alright is commonly used in written dialogue and informal writing, but all right is the only acceptable form in edited writing. Basically, it is not all right to use alright in place of all right in standard English.
