1. Using Punctuation Marks
Punctuation is the use of standard marks and signs in writing to separate
words into sentences, clauses, and phrases in order to clarify meaning.
Here are the punctuation marks that are most commonly used when writing
and the most typical way or ways they are used.
Examples are provided for each.
1. Period (.)
- Use a period at the end of a declarative sentence (a sentence which states
an idea). "That was a wonderful movie."
- Use a period to end an abbreviation. "I think that Mr. Williams is a great
teacher."
2. Question Mark (?)
- Use a question mark at the end of an interrogative sentence (a sentence
which asks a question). "Did you like that movie?"
3. Comma (,)
- Use a comma to separate three or more items in a series. "My history class
meets each Monday, Wednesday, and Friday."
- Use a comma to separate independent clauses in a sentence. "We wanted to
go to the beach, but it rained that day."
- Use a comma after introductory words or phrases in a sentence. "Certainly,
I have my homework right here."
- Use a comma to set off dates and addresses. "My friend Jane, who was
born June 18, 1992, lives in Akron, Ohio."
- Use a comma in appositives (an explanatory phrase).
“Mr. Rivera, my best teacher, gave me an award.”
- U se a comma between the names of a city and a state.
“I lived in Brooklyn, New York.”
- Use a comma to separate a noun in a direct address.
“Fred, help me with the desk.”
- Use a comma before or after a direct quotation to set off the words that tell
who is speaking. Danny said, “ That is my book.”
4. Semicolon (;)
- Use a semicolon when two independent clauses in a sentence are not
separated by a conjunction (such as "and").
"I like pizza; Carlos also likes pizza"
- Use a semicolon between independent clauses in a sentence that are
separated by any of the following transitional words or phrases: accordingly,
consequently, for example, for instance, furthermore, however, instead,
moreover, nevertheless, otherwise, and therefore. "I planned to study

2. Saturday morning; however, the power in our house went out due to a
storm."
- Use a semicolon when the items in a series of items contain commas. "I
have lived in Los Angeles, California; Boston, Massachusetts; Trenton, New
Jersey;
and Philadelphia, Pennsylvania."
5. Colon (:)
- Use a colon before a list that is preceded by a complete independent clause.
Some form of the word "follow" is often used in such a case. "On our next
vacation, we plan to visit the following countries: England, France, Italy,
and Greece."
- Use a colon to divide hours from minutes. "I have an appointment with the
doctor at 10:30 tomorrow morning."
- Use a colon following a Biblical chapter.

interjection is a word used to express strong feeling or sudden emotion).

7. Apostrophe (')
- Use an apostrophe to indicate a missing letter or letters in a contraction. "I
don't think she will win the election."
- Use an apostrophe plus the letter "s" to show possession. "Please take
good care of Brad's dog."
8. Quotation Marks (“ ”)
