when was ain’t added to the oxford dictionary

The word “ain’t” has a long history and was in common use in English for centuries before it was officially recognized in dictionaries. However, its inclusion in prestigious dictionaries like the Oxford English Dictionary (OED) came relatively late compared to other words. “Ain’t” was added to the Oxford English Dictionary in 1837, marking its formal recognition in authoritative English language references. Since then, it has been included in subsequent editions of the dictionary.
