title: Displaying the name of a child category without listing all childs
body: <p>I'm trying to display the name of a child category attached to a post using this function:</p>
  
  <pre><code>&lt;?php wp_list_categories('style=none&amp;orderby=id&amp;show_count=0&amp;use_desc_for_title=0&amp;child_of=39&amp;hide_empty=1'); ?&gt;
  </code></pre>
  
  <p>The problem is that it lists all the child category names of parent 39. I would only like to get the category name that is used by the post.</p>
  
  <p>Thanks in advance</p>
