This composition lesson discusses and illustrates the forms and functions of sentence patterns based on the four kinds of clauses: main (independent) clauses, adverb (subordinate) clauses, adjective (relative) clauses, and noun clauses, as well as elliptical clauses—elliptical forms of the four kinds of clauses. This lesson is first in a series of grammar lessons, for writers develop style as they become more familiar with clauses.
