This chapter discusses noun clauses, gerunds, and infinitives. It focuses on that clauses, noun clauses filling noun phrase slots, extraposing that clauses, wh- subordinates, and for/to. That can function as a subordinator linking two sentences together into a single sentence. Noun clauses differ from relative clauses in that a noun clause is the subject or object of the main clause, while a relative clause modifies a noun. Wh- words can also function as subordinators, linking two clauses together where the wh- word stands in for missing information.
