There are two different formats you can use. Using a verb as an example:

vocabulary {
   : verb {
      aliases = [talk, speak]
   }
   : verb {
      aliases = [lie, crouch]
   }
}

OR

vocabulary {
   : verb / aliases = [talk, speak]
   : verb / aliases = [lie, crouch]
}

The second format is more concise. For nouns, just replace "verb" with "noun".
