       <h3>Algorithm</h3>
 
       <p>This algorithm takes three required inputs and three optional inputs.
-        The required inputs an <tref>active context</tref>, an <tref>inverse context</tref>,
+        The required inputs are an <tref>active context</tref>, an <tref>inverse context</tref>,
         and the <i>iri</i> to be compacted. The optional inputs are a <i>value</i> associated
         with the <i>iri</i>, a <i>vocab</i> flag which specifies whether the
         passed <i>iri</i> should be compacted using the
