2. Let’s Review: What makes a
complete sentence?
It is a long fancy word, but an independent clause is simply a
complete sentence. It CAN stand alone. A complete sentence
has three essentials.
It has:
a subject (noun)
a predicate (verb)
and a complete thought! Example:
The sun shines brightly.
INDEPENDENT
C L A U S E = SUBJECT + PREDICATE
Is your sentence also a complete thought?
3. What then is a dependent clause?
A dependent clause is a
phrase that cannot
stand alone.
You’ll often be able to
recognize a dependent
clause because many
begin with a
SUBORDINATE
CONJUNCTION
STOP!

5. How to punctuate sentences with
subordinating conjunctions
Beginning of a sentence
When you have a dependent clause at the beginning of
the sentence, you ALWAYS have to add a comma after it.
As soon as it stopped raining, we saw a double
rainbow.
Dependent , + Independent
6. How to punctuate sentences with
subordinating conjunctions
End of a sentence
If you have a dependent clause in the back/end of the
sentence, you DO NOT USUALLY need a comma.*
We saw a double rainbow as soon as it stopped
raining.
Independent + Dependent
*On occasion you will need a comma when a dependent
clause is at the end of the sentence, but that depends on
style and clarity. For example, when the dependent clause
starts with “which” or “especially.”
7. How to punctuate sentences with
subordinating conjunctions
Middle of a sentence
When you have a dependent clause in the middle of a
sentence, you need commas on both sides of the
dependent clause. *
Frank, who loves to travel, will be our guide.
Sub, + Dependent, + Predicate
8. What Is a Run-on Sentence?
A run-on is when you put two
complete sentences together without
any punctuation in between.

9. What Is a Comma Splice?
A comma splice is a sentence error caused by
putting just a poor, weak comma between
two complete sentences.

11. Now you try! Use a period to correct
these run-ons and comma splices.

12. Link them with a semicolon; this creates two complete
sentences just as a period does, but the second sentence
doesn’t start with a capital letter.
The sentences MUST be related in order to use a
semicolon.

13. How Can I Correct Comma Splices and

Join the two sentences with a comma and
one of the COORDINATING CONJUNCTIONS.

Run-ons? The 4th way is to…
End the first sentence with a semicolon
and begin the second with a
conjunctive adverb or transitional.

STOP
16. Now you try! Use a semicolon and a transitional
word like therefore or however to correct this
comma splice.

sometimes get discouraged.
