> Usage notes
According to the American Heritage Dictionary, Fourth Edition (2000), the form ax is now associated with African American Vernacular English, but in the past it was common among “white” Americans as well, especially in New England, and is a feature of some British dialects. It was a common word in English for a thousand years (Chaucer used both forms interchangeably), but is now stigmatized as nonstandard. This is similar to the case of words like ain't which were also acceptable in the past.
