Punctuation rules can confuse the best of us.
When do we use semi-colons? What are the rules for commas? When do we use apostrophes and quotation marks?
Use this guide to help you!
1. Ending Sentences
Use these to end declarative sentences
and imperative sentences
2. Abbreviations (shortened forms of words).
- The sun is shining today.
- Open the door.
- I spoke with Sgt. Johnson about the troops.
Question Marks ?
The punctuation rules for question marks are very simple. In fact, there is really only one rule!
1. Ending Sentences
These end interrogative sentences
This kind of sentence asks a question. Any time you ask a question, end the sentence with a question mark.
- Should I use a question mark on this sentence? (Yes!)
Exclamation Marks !
1. Ending Sentences
Use these at the end of exclamatory sentences
, which are sentences that show emotion.
You can use either an exclamation mark or a comma after an interjection
Comma Rules ,
Commas show your reader that there is a pause in the sentence they are reading.
It seems that commas have more punctuation rules than any other form of punctuation. I've narrowed it down to seven rules for you.
When you list three or more things, use commas between the words.
2. Three or More Adverbs or Adjectives
- I would like grapes, apples, and cookies.
- Are we having fish, chicken, or beef for dinner?
- This is a warm, fuzzy, pink sweater. (adjectives)
- My new car ran quietly, quickly, and smoothly. (adverbs)
When a number is over 999, use commas to separate the numbers.
4. Dates and Addresses
- I paid $3,500 for my new boat.
- The house is $600,000.
- September 1, 2009
- I live in Saint Paul, Minnesota.
- Send the package to 5154 Smith Street, Los Angeles, California, 92674.
When you are quoting someone's exact speech, you must use quotation marks and a comma.
6. Joining Independent Clauses
- My sister exclaimed, "You came home!"
- "I missed you," I said.
When you join two independent clauses, use a comma and a coordinating conjunction
When you have two independent clauses joined only by a comma, it's called a comma splice. Avoid comma splices
7. Introductory Words and Clauses
- I love cats, but I also love dogs.
- Can you come, or should I go?
- My sister had a ballet performance, and my brother had an orchestra concert.
Use these to separate two complete sentences that are closely related.
- I went to the play; my cousin was the main actor.
1. Introducing Lists
2. Introducing Single Items
- There are three ways that I love to relax: reading magazines, practicing yoga, and taking baths.
You can use a colon to introduce a single thing when you want to emphasize it.
3. Between Two Complete Sentences
- After shopping for eight hours, I finally found them: the perfect pair of jeans.
This is only a legit move if the second sentence states a logical consequence of whatever is stated in the first sentence.
- Jim ate brownies constantly: He gained seven pounds.
I would argue that the punctuation rules for apostrophes are some of the most commonly misused punctuation rules ever.
While misusing apostrophes can make for some funny signs (We Sell Carpet's!), you'll probably want to avoid misusing them.
The rules are pretty simple. There are only two times when you should use apostrophes.
When you want to make something possessive (to show ownership), use an apostrophe.
- This is Mark's cat. (The cat belongs to Mark.)
- That is the television's remote control. (The remote control belongs to the television.)
- Don't ever go into the teachers' lounge. (The lounge belongs to the teachers.)
Contractions use apostrophes to stand in the place of missing letters.
- I can't stand the smell of bananas! (can't = cannot)
- I won't go with you. (won't = will not)
- The students shouldn't use cell phones in class. (shouldn't = should not)
Quotation Marks ""
If you're up for a laugh, the "Blog" of "Unnecessary" Quotation Marks
has lots of funny misuses of quotation marks.
1. Quoting Exact Speech
Whenever you quote someone's exact speech, you must use quotation marks.
- The police officer said, "Where are you going?"
- "I'm going to work," I replied.
Use quotation marks to show the titles of magazine articles, chapters, short stories, essays, poems, and songs.
- "Columbus" is a great poem.
- Our homework tonight is to read Chapter 6, "The Lovely Rose Garden."
- Sydney sang "The Star Spangled Banner" at the football game.
