+## Parenthesis  
+Parenthesis are used to wrap expressions. They may used to enforce e.g. additions to be executed before multiplications. Parenthesis surrounding [Functions](#function) will **not** be parsed into AST nodes.
+
+```javascript
+// e.g. (
+{
+  type: 'Parenthesis',
+  value: '('
+}
+```

 ## URL
 URL is used for any URI-type string. *It is not validated by the parser!*
