title: Are there published generative grammars for natural languages?
body: <p>I have some ideas to do with natural language processing. I will need some grammars of the</p>
  
  <pre><code>S -&gt; NP VP
  </code></pre>
  
  <p>variety in order to play with them.</p>
  
  <p>If I try to write these rules myself it will be a tedious and error-prone business. <strong>Has anyone ever typed up and released comprehensive rule sets for English and other natural languages?</strong> Ideally written in BNF, Prolog or similar syntax.</p>
  
  <p>My project only relates to context-free grammars, I'm not interested in statistical methods or machine learning -- I need to systematically <em>produce</em> Engligh-like and Foobarian-like sentences.</p>
  
  <p>If you know where to find such materiel, I'd very much appreciate it.</p>
