 The usage of ain 't is a perennial subject of controversy in English. Ain't is commonly used by many speakers in oral or informal settings, especially in certain regions and dialects. Its usage is often highly stigmatized, and it may be used as a marker of low socio-economic or regional status or education level. Its use is generally considered non-standard by dictionaries and style guides except when used for rhetorical effect, and it is rarely found in formal written works.
