This document provides information about conjunctions and subordinate clauses. It defines conjunctions as words that link phrases and clauses, distinguishing between coordinating conjunctions like "and" and "or" and subordinating conjunctions like "because" and "when." Examples are given of sentences containing subordinate clauses introduced by subordinating conjunctions. Students are asked to identify conjunctions in passages and practice rearranging sentences to change the placement of subordinate clauses. Slang, colloquialisms, prefixes, suffixes, and roots are also briefly discussed.
