Punctuation, Italics, and Capitalization

Good punctuation can make or break your essay. With good punctuation, you can create an essay that flows well and is interesting to read. Without it, your essay will be choppy and confusing. You do not need to memorize all of this, it is just meant to be used for reference. 

01

The Period

Image by Hannah Olinger

A period is used

  • To end a statement.​

          e.g. I am 15 years old.

  • To end a mild command.

          e.g. Meet me at the park.

  • To end an indirect question. 

          e.g. She asked why I was at the park. 

  • With most abbreviations.

          e.g. 59th Ave., Dr., p.m.

Note: Abbreviations for organizations, corporations, and government agencies do not usually use periods.

           e.g. IBM, CIA, USMC 

Pronounceable acronyms do not need periods.

          e.g. UNESCO, WHO

02

The Comma

A comma is used: (Buckle in there's a lot of uses)

  • To separate words, phrases, and clauses in a series.

e.g. His vision, strength of character, and enterprise have brought about great changes.​

  • To separate parts of a date or address or to set them apart from the rest of the sentence.

e.g. On March 6, 1978, Joe arrived in Dallas, Texas.

  • To separate a short question from a statement when the question is dependent upon the statement for its meaning.

  • e.g. It was Paul who bought the radio, wasn't it?

  • To set off words of direct address.

e.g. "Ann, can you type this paper?"

No, Joe, someone else will have to type it."

  • To set off the name of the speaker from a direct quotation.

e.g. "I hate to go home without any fish," said Jim, "but today the fish just aren't biting."

  • To separate two adjectives modifying the same noun equally if the adjectives could be joined by a conjunction. Adjectives should not be separated with a comma when the one nearer the noun is more closely related to the noun.

e.g. A tall, thin figure appeared in the doorway.

The figure was tall and thin.

  • To set off introductory verbal phrases modifying the subject of the sentence.

e.g. Driving carefully over the slippery pavement, we finally reached our house. (participle)

After unpacking the car, we took it to the garage. (prepositional phrase)

To advance in the profession, one must work hard. (infinitive)

  • To separate the main clauses in a compound sentence.

e.g. We finished our homework, and we listened to music for the rest of the evening.

  • To set off an adverb clause at the first of a sentence.

e.g. When I finished the assignment, I walked to the front of the room and turned it in.

Note: Adverb clauses appearing at the end of the sentence do not need commas.

  • To set off introductory prepositional phrases if they are lengthy, if several phrases are used together, or if the comma is needed for clarity. A single prepositional phrase at the beginning of a sentence does not usually require a comma.

e.g. At the beginning of the year 1950, they set off for their trip.

In 1950 they set off for their trip.

  • To set off parenthetical expressions.

e.g. He has, we understand, been very successful.

You are, however, very fortunate to obtain the position.

He is, to tell the truth, unable to meet the obligation.

  • To set off adjectives that follow the noun they modify.

e.g. The child, carefree and happy, wandered into the forest.

  • To set off contrasting expressions from the rest of the sentence.

e.g. It was John's attitude, not inefficiency, that lost him the job.

  • To set off an appositive from the rest of the sentence.

e.g. George Powers, a former football star, gave a talk.

  • To set off nonrestrictive adjective clauses from the rest of the sentence.

e.g. The boy, who is my friend, will come to visit us.

Note: The conjunctive adverb is preceded by a semicolon and followed by a comma.
