Knowing a word’s part of speech helps you understand how to use that word. But you also need to look at the part the word plays in a particular sentence. Consider, for instance, the word description.
Description is a noun in both sentences, yet in the first it serves as the subject of the verb conveys, while in the second it serves as the direct object of the verb read.
