The document defines and provides examples of different types of clauses:
- Main clauses are independent and can stand alone as a sentence, while subordinate clauses cannot stand alone and must be joined to a main clause.
- Coordinating clauses join two independent clauses of equal importance with conjunctions like "and" or "but".
- Subordinate clauses include noun clauses that act as nouns, relative clauses that provide additional information about a noun, and adverbial clauses that modify verbs, adjectives or other adverbs by describing place, time, condition and more.
