University College London: Clauses and Sentences

This section of an online English-grammar book introduces and provides examples of different types of clauses. Because this is from a British source, it uses different terms to identify the types of clauses, calling an independent clause, the matrix clause and the dependent clause, the subordinate clause, and identifying a third type, the superordinate clause. This is a 7-page tutorial on clauses and sentences; click through the page numbers at the top right to work through the tutorial.
