What did early draft introduce ?
English has a number of fused relative pronouns , such as " what " , " whatever " , and " whoever " , but all can introduce other kinds of clauses as well ; " what " can also introduce interrogative content clauses ( " I do not know what he did " ) , for example , and both " whatever " and " whoever " can introduce adverbials ( " Whatever he did , he does not deserve this " ) .
