If a cow is in the fields and you want it to give milk, you don’t talk to it about the various kinds of grass to eat, analyzing with it the soil that the grass grows in, and you also don’t try to make it create milk before eating any grass. You just let it eat grass all day.
In the same way, we don’t talk to our students about the language we are teaching them, we don’t analyze the structure of the language that the words exist in, and we also don’t make them speak before they have heard the language a lot. We just let them listen to and read the language all the time, and, soon enough, they produce good writing and good speech.
