1. Sentences: Simple, Complex, & Compound

2. Review: Clauses
To understand certain types of sentences, you have to understand certain types of clauses, as studied in our last unit.
Remember: an independent clause is a fancy name for a sentence.
A dependent clause is a group of words that has a subject and predicate, but cannot stand alone (it doesn’t express a complete thought).

3. What is a SIMPLE Sentence?
is a stand-alone
independent clause
without any
dependent clauses.

4. Sample SIMPLE Sentences

Independent Clause / Simple Sentence #2:
My brother and I are tired.
Independent Clause / Simple Sentence #3:
The trees bent and swayed in the wind.
Independent Clause / Simple Sentence #4:
A small, furry squirrel ran up a pole.
(Notice how sentence #2 has compound subjects and
sentence #3 has compound predicates.)

5. What is a COMPLEX Sentence?

independent clause

dependent clauses.
