After word-level tokenization, we have a list of words that are used in the text. Some of these words are common words that are expected to appear in almost every document. These words do not provide any additional insight into the documents that they appear in. These words are called stopwords. They are usually removed in the data-processing phase. Some examples of stopwords are was, we, and the.
