2 Complex SentencesRemember all clauses are composed of a subject (noun) and a verb.Some clauses are independent meaning they can stand alone as a complete thought. This is a sentence.Other clauses are dependent (also called subordinate) meaning that they do not complete a thought but depend on an independent clause to complete the thought.
3 Complex SentencesUsed alone, dependent clauses are fragments and are errors in writing.Used with an independent clause, they help add depth and complexity to the structure of the sentence.There are three types of complex sentences: adverb clauses which answer how, when, why, where, to what extent; adjective clauses, which answer which one, what kind and how many, and noun clauses which function in the same capacity as a noun.
4 Adverb ClausesAdverb clauses answer the questions how, when, where, why, to what extent.They begin with subordinating conjunctions: Some common subordinating conjunctions are since, so that, when, whenever, where, wherever, if, because, after, before, although, even though.When an adverb clause begins a sentence, writers should use a comma.
5 Adverb Clauses Possible combinations: When a journey begins badly, it rarely ends well.A journey rarely ends well when it begins badly.Notice the position of the adverb clause and where the comma is used.
6 Adjective ClausesAdjective clauses answer the questions: which one, what kind, how many.Adjective clauses begin with relative pronouns: who, whom, which, that, where.Adjective clauses are either non-essential, which means that they are not necessary to the meaning of the sentence and are set off by commas, or essential, which means that they are necessary to the meaning of the sentence and are not set off by commas.
7 Adjective ClausesExample of non-essential adjective clause: Even his eyes, which had been young, looked old.Example of essential adjective clause:Scientists who explore the sea face many hazards.
8 Noun ClausesNoun clauses function in the same way that a noun functions: subject, predicate nominative, direct object, indirect object or object of the preposition.You will not use commas with noun clauses because they will function the same as the noun functions in a sentence.Noun clauses may begin with words such as when, that, where, who, whichever, whoever, how.
