Punctuation and Capitalization
What is Capitalization?
Capitalization occurs when the first letter in a word is an upper case letter.
For example, the first word in this sentence contains a capital F.
Why do we use Punctuation and Capitalization?
Marks of punctuation and capitalization help readers understand and interpret sentences better. Some marks are required to prevent misreading and some are optional and depend on what the writer wishes to achieve. For example ending a sentences with an exclamation mark rather than a period.

Exclamation Point '!'

Be careful not to use exclamation mark too often.
What a wonderful day it is!

Comma ','See comma rules details
1. A comma separates things in series. (list of items)
I ate pizza, a burger, and ice cream.
I like reading, listening to music, taking long walks, and visiting my friends.
This is one of the most common uses of a comma. Notice that a comma is included before the conjunction 'and' which comes before the final element of a list.
2. A comma separates an interruption from the rest of the sentence.
Mr. Walker, our teacher, is very clever.
3. A comma separates two independent clauses that are connected by a conjunction such as 'but'.
They wanted to purchase a new car, but their financial situation would not allow it.
I would really enjoy seeing a film this evening, and I'd like to go out for a drink.
4. Separate phrases (clauses)
In order to qualify for your certificate, you will need to take the TOEFL exam.
Although he wanted to come, he wasn't able to attend the course.
5. Introduce a direct quote (as opposed to indirect speech i.e. He said he wanted to come...).
The boy said, "My father is often away during the week on business trips."
His doctor replied, "If you don't stop smoking, you run the risk of a heart attack."
1. A colon shows the reader that a list or explanation follows.
I will need the following items:
scissors, paper, glue, and paint.
He had many reasons for joining the club:
to get in shape, to make new friends, to lose some weight, and to get out of the house.
2. To introduce a direct quote (a comma can also be used in this situation)
He announced to his friends:
"I'm getting married!"
She cried out:
"I never want to see you again!"
The semicolon signals a pause longer than a comma but briefer than a period.
There are two uses for a semicolon:
1. To separate two independent clauses. One or both of the clauses are short and the ideas expressed are usually very similar.
He loves studying;
he can't get enough of school.
What an incredible situation;
it must make you nervous.
2. To separate groups of words that are themselves separated by commas.
I took a holiday and played golf, which I love;
read a lot, which I needed to do;
and slept late;
which I hadn't done for quite a while.
They plan to study German, for their travels;
chemistry, for their work;
and literature, for their own enjoyment.
Do not use a capital letter after a semicolon, unless it is followed by a proper noun.
Quotation Marks (double " or single ')
1. Quotation marks are used to identify the exact words of a speaker.
President Bush said, "
We will not tire, we will not falter, and we will not fail."
2. For speech within speech, the other style is used as inner quotation marks:
'Dave said, "Good afternoon, Frank"', recalled Frank.
Place the punctuation marks outside quotation marks, unless they are logically parts of the quotation.
His answer to this was "no"; but two years later, he changed his mind.
Did he say "yes" or "no"?
