title: adding singular plural combinations to SpaCy
body: <p>How do I add new lemmas to SpaCy. For instance, new singular-plural nouns.</p>
  
  <p>Example: 
  Kirana = Singular
  Kiranas = Plural</p>
  
  <p>I want to add it to SpaCy so that when a sentence contains "Kiranas", Kirana will show up as its lemma.</p>
