In my past few years of going to school, there were plenty of prescriptive rules that my teachers have taught my class and I. I was repeatedly told that there was a difference in words with punctuation. for example, in elementary school, I was having a hard time understanding that “you’re” and “your” are two completely different words. Another way the prescriptive rule was taught to me was by “their” and “there”. I genuinely had a rough time understanding the differences between such words but I overcame those obstacles. in my school experience, I was indeed told that “ain’t” was less valid than “aren’t” because my teachers said that “ain’t” was not even a real word. In high school, people were so into talking with lingo and that’s what had set the teachers off. so many students started talking like one another and this is what led to the teachers always telling us students that most of the words we used were not proper. Although, I would say that my teachers correcting me has helped me in my life today. if it wasn’t for them correcting me then I would not be as professional as I am now. I also wouldn’t have been using the correct words in certain sentences. I have stopped using the wrong words in phrases in my sentences now. I also look out for the correct punctuation. over all, I don’t remember many of my teachers ever explaining double negative.
