Why use characters in example sentences?

As we’ve all experienced, our ability to learn and remember is significantly enhanced when we learn about something that arouses our emotions, rather than learning content that is cut and dry. For this reason, Knowji, unlike other vocabulary apps or books, uses a persistent set of interesting, complex characters in our example sentences to help the learner foster a deeper, more emotional context around the words they are learning.
