    <p class=default>
      
        The complex group of things we typically perform when speaking. J. L. Austin famously 
        distinguished the simple 
      
      
        <b>locutionary act </b>
      
      
        of saying something meaningful, the force of the 
      
      
        <b>illocutionary act </b>
      
      
        of employing this language for some purpose, and the further 
      
      
        <b>perlocutionary act </b>
      
      
        of having an actual effect on those who hear the utterance.
