Why is grammar needed in English?
I have been studying English since elementary school in the fourth grade. My teachers always teach me about grammar. They told me that grammar is the important one for making a good sentence. However, untill now I still find it difficult to apply the grammar in every my essay. Moreover, I often hear someone who is speaking in english without the use of proper grammar and the conversation can still run well. So, why is grammar needed in English?
Thanks in advance~ :))
