THE RELATIVE PRONOUN AND THE INTERROGATIVE PRONOUN
[219.] Sentences are simple, compound, or complex.
a. A simple sentence is a sentence containing but one statement, that is, one subject and one predicate: The Romans approached the town.
b. A compound sentence is a sentence containing two or more independent statements: The Romans approached the town | and | the enemy fled.
Note. An independent statement is one that can stand alone; it does not depend upon another statement.
c. A complex sentence is a sentence containing one independent statement and one or more dependent statements: When the Romans approached the town | the enemy fled.
Note. A dependent or subordinate statement is one that depends on or qualifies another statement; thus the enemy fled is independent, and when the Romans approached the town is dependent or subordinate.
d. The separate statements in a compound or complex sentence are called clauses. In a complex sentence the independent statement is called the main clause and the dependent statement the subordinate clause.
