The definiton of grammar is the whole system and structure of a language. It's basically the entire language, which makes grammar very important. Although, I don't really like grammar, I don't really mind. I started learning grammar, the parts of speech and functions, in 5th grade and up ever since. This makes it way easier for me to participate in class and to understand everything faster. Also the reason that I now kind of like it, because if you're good at something, you like it. But grammar is hard and it took me 5 years to get where I am now, so what I'm trying to say: All you have to do to learn grammar is to repeat. Repetition, repetition, repetition. When you understand a certain function or part of speech really well, you challenge yourself by making the sentence harder. Then again, repetition, repetition, repetition. I still have a little difficulty dissecting some sentences, which is why I'm glad that we dissect them in class afterwards. The only thing we didn't do, was the homework sentences together in class, so I hope those 5 years of practise hasn't gone to waste and I'll have 90% right.
