| More on nestingTask C - relative clauses (RCls) in 'The House that Jack Built'It is arguable that one of the functions of the nursery rhyme 'The House 
        that Jack Built' is to teach young children how to use relative clauses. 
       Look at one of the sentences from the nursery rhyme 
        below (we have removed the lineation to make it easier for you to analyse) 
        and, starting from the right-hand end, put brackets around each of the 
        relative clauses.  To get you started, we have put brackets around the rightmost RCl for 
        you. When you have sorted out your brackets and worked out what is going 
        on in the sentence, compare your effort with ours. 
 our answer  
        Our answer:
           
            | S | P | C |   
            | This | |  is |  |  the dog (that chased the cat (that 
                killed the rat (that lived in the house (that Jack built)))). |  Overall, this sentence has a very simple SPC structure. But the NP 
          acting as the Complement of the sentence, and which has 'dog' as its 
          headword has a relative clause postmodifying it (beginning with the 
          relative Subject pronoun 'that'). That clause has the structure SPO, 
          but the NP acting as O in the RCl then has another RCl inside that (with 
          its own relative Subject pronoun), and so on. It is this ability to 
          nest clauses again and again inside other clauses or phrases which enables 
          us to construct truly complex sentences. It is easiest to describe exactly what is going on by starting from 
          the right, with the most deeeply nested RCl. 
           
            The RCl 'that Jack built' postmodifies 'house',  
            'that lived in the house that Jack built' postmodifies 'rat',  
             'that killed the rat that lived in the house that Jack built' 
              postmodifies 'cat' and,  
             'that chased the cat that killed the rat that lived in the house 
              that Jack built' postmodifies 'dog', the headword of the Complement 
              NP. If you would like to look at the nursery rhyme then try
