Does correct usage of grammar include using standard vocabulary?
This question has been debated for decades by linguists. Some say that the only form of correct English grammar is standard forms, while others argue that, because the English language is developing so fast due to technology and other means, that there is no ‘correct’ way sticking to grammar rules. But to answer your question, it would totally depend on what and/or who you are writing for. If you are writing a business or very formal letter, you should stick to Standard English throughout, whereas if you are writing a magazine article or something similar, then you may break some grammar rules. Many poets and article writers for newspapers such as The Guardian (such as Charlie Brooker) are prime examples of people who do not use standard vocabulary. EDIT: “I a goin” and “I ay goin” Again, it really depends on what type of text it is. It would be viewed as grammatically incorrect if you wrote it in an exam, but wouldn’t be considered incorrect, to say the least, in things like articles
