+          be able to understand new words from context alone, as they'll have more instances

+          A <em>complex word</em> is a word made up of at least two morphemes. 
+          Conversely, a <em>simple word</em> consists of only one. 
+          For example, "bookishness" is a complex word with morphemes "book", "ish", and "ness";
+          "active" is a simple word with just one morpheme: "active".
+        </p>
+        <p>
+          Having a healthy mixture of simple and complex words is an important aspect of variety
+          in your writing. Replacing complex words with simple words can make your story easier
+          to understand, while replacing simple words with complex words can more efficiently
+          pack more context and information into the words you choose to use.
