adjective
Two kinds of participles:
1. Present participles—end in –ing
2. Past participles—end in –ed, -d, or –t

Subordinate Clauses

Dependent clauses cannot stand alone in a
sentence.

meaning of the sentence, a comma is needed
before and after it.
Example:
Jimmy Carter, whose full name is James Earl Carter,
prefers to be known as Jimmy.
Appositives
A word that means the same thing as the noun it follows. It
usually explains or identifies the noun.

flavor.
NOTE: When the appositive is essential to the meaning of the
sentence, no comma should be used.

The blues singer Bessie Smith wrote the song “Backwater
Blues.”
Words Used in Direct Address
When someone speaks directly to another
person, using that person’s name, commas
precede and follow the name.
Examples:
Mrs. Clarkson, I just want to get to the beach.
Can you tell me, Hazel, when the next bus is
due?
Parenthetical Expressions
Words that are not grammatically related to the
rest of the sentence (like words used in
PARENTHESES).
EXAMPLES:
To tell the truth, in my opinion, in fact, for
example, however, etc.
What, in her opinion, is the best closing hour?
#5. Use a comma after certain introductory
elements.
A.)Word such as well, yes, no, and why when
it begins a sentence.
• Why, you really should know that!
• Well, I don’t.
Note: Words such as well, yes, no, and why are not
followed by a comma if they do not interrupt the
sentence; that is, if no pause follows them.
Example: Why is Rebecca early?
Rule #5 Continued
B.)Use a comma after an introductory phrase or

long prepositional phrase or if two or more
phrases appear together at the beginning of a
