The word, "ain't," is not standard English. Also, the correct verb form is "broken."
If it isn't broken, don't fix it.
The error in the sentence "If it ain’t broke, don’t fix it" is the use of the contraction "ain’t". The word "ain’t" is considered non-standard English and is generally discouraged in formal writing or professional settings. It is a colloquial term that combines "am not", "is not", or "are not". In more formal writing or communication, it is recommended to use the proper contractions or their expanded forms, such as "isn't" or "are not". So, in this case, the error is the use of "ain't".
