Back in middle school my grammar and wording were always corrected by the teachers. They corrected me about a lot of words that I shouldn’t have used. For instance I used gonna a lot. I used to say “ I’m gonna go to the park” or “I’m gonna go home.” Or I would use ain’t, and say “ I ain’t gonna go to school” However my teachers always corrected my vocabulary/grammar, instead of “gonna,” my teacher told me to use “going”. Instead of “ain’t” I had to use “aren’t”. My teacher thought that these words were improper and used the excuse “In high school/college they will not accept this type of grammar” I can agree the words “ain’t” and “gonna” aren’t formal however I do believe now they aren’t improper words to use though. I wouldn’t stop using these words in my daily life or my writing assignments, especially since linguistics makes me have more free will and there’s no such thing as rules with descriptivism linguistics. However, when I write formal essays I do want to be proper and write formally, and use different words.
