to be written as "ain't", which first appears in writing in 1749. By the time "ain't" appeared, "an't" was already being used for "am not", "are not", and "is not". "An't" and "ain't" coexisted as written forms well into the nineteenth century. "Han't" or "ha'n't", an early contraction for "has not" and "have not", developed from the elision of the "s" of "has not" and the "v" of "have not". "Han't" also appeared in the work of English Restoration playwrights. Much like "an't", "han't" was sometimes pronounced with a long "a", yielding "hain't". With H-dropping, the "h" of "han't" or "hain't" gradually disappeared in most dialects, and became "ain't". "Ain't" as a contraction for "has not"/"have not" appeared in print as early as 1819. As with "an't", "hain't" and "ain't" were found together late into the nineteenth century. Some other colloquial and dialect contractions are described below: "Bain't" or "bain't", apparently a contraction of "be not", is found in a number of works employing eye dialect, including J. Sheridan Le Fanu's Uncle Silas. It is also found in a ballad written in Newfoundland dialect. "Don't" is a standard English contraction of "do not". However, for some speakers "don't" also functions colloquially as a contraction of "does not": Emma? She don't live here anymore. This is considered incorrect in standard English. "Hain't", in addition to being an antecedent of "ain’t", is a contraction of "has not" and "have not" in some dialects of English, such as Appalachian English. It is reminiscent of "hae" ("have") in Lowland Scots. In dialects that retain the distinction between "hain't" and "ain't", "hain't" is used for contractions of "to have not" and "ain't" for contractions of "to be not". In other dialects, "hain't" is used either in place of, or interchangeably with "ain't". "Hain't" is seen for example in Chapter 33 of Mark Twain's The Adventures of Huckleberry Finn: I hain't come back—I hain't been GONE. ("Hain't" is to be distinguished from "haint", a slang term for ghost (i.e., a "haunt"), famously used in the novel To Kill a Mockingbird.) Contractions and inversion In cases of subject–auxiliary inversion, particularly in the formation of questions, the negative contractions can remain together as a unit and invert with the subject, thus acting as if they were auxiliary verbs in their own right. For example: He is going. → Is he going? (regular affirmative question formation) He isn't going.
