            The higher percentage of reused words you have, the more likely a reader will
            be able to understand new words from context alone, as they'll have more instances
            in which they can infer a meaning from that word's surroundings.
          </p>
          <p>
            Having a higher number of reused words can make text much easier to read and understand,
            but a limited vocabularity may result in repetition and bland writing. Having a higher
            number of unique words may indicate more effective word choice, but can also be indicative
            of jargon.
