Yes, knowing and applying grammar rules in English is important. However, if you don’t know how to use words and phrases, you will confuse your reader far more than with grammar mistakes. Words are like the “building blocks” of a language, and they are the primary way that you express your meaning to your reader.
So, spending time building your vocabulary will benefit you greatly in your academic writing activities. The more vocabulary you know, the better you will be able to express your ideas in speaking and writing.
