Etymologies
- 1. From the earlier form an’t, a contraction of am not, are not, and is not. The shift from IPA: /ænt/ to IPA: /eɪnt/ parallels a similar change in some dialects with can’t. In other dialects the pronunciation shifted to IPA: /ɑːnt/, and the spelling aren’t, when used to mean “am not”, is due to the fact that both words are pronounced IPA: /ɑːnt/ in some non-rhotic dialects. Historically, ain’t was present in many dialects of the English language, but not in the southeastern England dialect that became the standard, where it is only found in the construction aren’t I?.

singlestar Despite the many convincing arguments for ain't as a contraction for 'I am not', I find myself cringing at the thought of it becoming a universally accepted part of the English language. Perhaps that is because it evokes images of illiterate hillbillies and other uneducated classes of society. Unfortunately, it is those very people who drive the change in language. Misuse of words and slang become commonplace and eventually wind up in the dictionary, thus language evolves. I guess I have to live with it but liking it is, to quote another of my pet peeves "a whole nother thing"! May 20, 2009

somescram The word "ain't" appears in Herman Melville's "Moby Dick." I'd say that's about all the support the English languages needs for its official inclusion in the language. May 26, 2008

stpeter Ain't is a contraction for "am not". Another form is "amn't" but that's hard to pronounce, no? It was further shortened to "a'n't" or "ain't". We're accepting of "we aren't" in the first person plural, "they aren't" in the third person plural, "he isn't" and "she isn't" and "it isn't" in the third person singular, and "you aren't" in the second person singular and plural. So why the resistance to "I ain't" in the first person singular? Granted, the extension of "ain't" to the second person singular (cf. the song "Is You or Is You Ain't My Baby" by Billy Austin and Louis Jordan) and to the third person singular (cf. "It Ain't Me Babe" by Bob Dylan) is problematic, albeit fun. But as far as I can see, "I ain't" is fair game. Jan 14, 2007
seanahan What is wrong with this word? It has been part of Standard English since at least the time of Twain, and will continue to be so. It is not acceptable written English, but then many things people say aren't. Jan 8, 2007
aftenthurston I don't know who thought that it would be a good idea to officially make that a word, but they should be tarred and feathered for it! Jan 8, 2007
