title: Regex - how to exclude single word?
body: <p>I am using <a href="http://www.position-absolute.com/articles/jquery-form-validator-because-form-validation-is-a-mess/" rel="noreferrer">http://www.position-absolute.com/articles/jquery-form-validator-because-form-validation-is-a-mess/</a> for validation. Validation rules are defined in a following way:</p>
  
  <pre><code>            "onlyLetterSp": {
                  "regex": /^[a-zA-Z\ \']+$/,
                  "alertText": "* Only letters"
              }
  </code></pre>
  
  <p>I would like to add new rule, which will exclude one single word. I have read some similar questions on StackOverflow and tried to declare it with something like this</p>
  
  <pre><code>"regex": /(?!exclude_word)\^[a-zA-Z\ \']+$/,
  </code></pre>
  
  <p>But it didn't work. Can you give me some advices how to do it?</p>
