Vocabulary is important as it is the basis for reading comprehension. Without a wide range of vocabulary, the words the writer has specifically written for the audience lose its meaning. With more vocabulary that you know, the better you are able to comprehend. With a larger vocabulary, you can be open to a wider range of reading. It’s the key to understanding what you learn from hearing and reading. Then with a rich vocabulary, you are able to communicate what you explicitly mean through listening, speaking and writing, just in words. For example, when a writer describes a character as being “morose,” the writer wants you to know that the character isn’t just sad, but rather sad to the point of near depression level. So there is that to consider.
