You can evaluate the rhetorical devices people use as well as how these can enhance their meaning and communication by paying attention to the purpose of what the person is saying as well as the form, audience and constraints. The purpose is the reason the person is saying what they’re saying, it can also include background information. The form is how the message is conveyed, in person, on FaceTime, by a call, or by text. The audience is who the message is targeted to and the constraints go hand in hand with this because the constraints are things the person cannot do or say. Gee says that someone can speak with perfect grammar and be “wrong nonetheless”, meaning that even using perfect grammar, a person needs to learn how to properly and effectively get their message across to the designated audience. I think both proper grammar and effectively conveying the point of what you want to say were always taught in school and so I am not surprised to see both becoming very important as I advance in my writing.
