        <p>
          There are a lot of pros and cons to reusing words. For more complex words, reuse is a great way to ensure your reader
          picks up on definition and tone with each context. On the other hand, reusing simpler or more repetitive words can
          also have a negative impact on some readers.
        </p>
        <p>
          The following tables show your most-used words in various categories. Each table excludes the most common 175 words
          (a, an, and, as, but, <em>etc.</em>) in the English language, known as "stop words".

            Sentence length can be a powerful tool in your writing and you should
            use it purposefully. Longer sentences can lure a reader in, while shorter,
            more stacatto sentences keep that attention with fast-paced action.
          </p>
          <p>
            This chart shows the length, in words, of each sentence through your
            document. Groups of shorter sentences likely read faster, while groups
            of longer sentences may be dense or hard to read.
