Punctuation tells the reader how to move.
Eleven marks do almost all the work in English writing — periods, commas, semicolons, and more. Learn what each one signals, then watch a few of them at work.
A mark for every pause
Every mark tells the reader how to move through a sentence — where to pause, where to stop, where a list begins. Open each card to see the pattern and real examples.
It ends a declarative or an imperative sentence.
It also closes most abbreviations, like "Dr." or "Mr."
He went to the store.
Dr. Smith is our family doctor.
Please close the door.
It separates items in a simple list, or an introductory phrase from the main clause.
It sets off non-essential information — detail you could remove without changing the core meaning.
She bought apples, oranges, and bananas.
When I arrived, they were already there.
My brother, who lives in New York, is visiting us.
It joins two independent clauses without a conjunction — each side could be its own sentence.
It also separates items in a complex list whose items already contain commas.
I have a big test tomorrow; I can’t go out tonight.
We visited Paris, France; Rome, Italy; and Berlin, Germany.
What comes before it must be a complete independent clause.
What follows explains, lists, or quotes what came before.
She needs to buy three things: bread, milk, and eggs.
He had one major flaw: impatience.
It shows who or what something belongs to: "Sarah’s book."
It marks a missing letter in a contraction: "don’t" for "do not."
Sarah’s book is on the table.
Don’t forget to call me.
Mind your p’s and q’s.
They wrap a speaker’s exact words or a quoted passage.
They also mark the titles of short works, like poems or articles.
She said, “I’ll be there soon.”
I just read “The Tell-Tale Heart” by Edgar Allan Poe.
It signals excitement, urgency, or a raised voice.
Overusing it in writing weakens its impact — save it for real emphasis.
Watch out!
That’s amazing!
It replaces the period at the end of any direct question.
It never combines with a period at the end of the same sentence.
Where are you going?
Did you finish your homework?
The information inside could be deleted without changing the main sentence.
Punctuation for the main sentence goes outside the closing parenthesis.
He finally answered (after taking five minutes to think).
The recipe calls for sugar (a cup and a half).
It joins two words acting as one describing word, like "well-known."
It also splits a word at the end of a line, or joins a prefix to a word.
She is a well-known author.
Re-enter your password.
The em dash (—) marks a dramatic pause or break in thought; the en dash (–) is shorter and marks a range.
Unlike parentheses, a dash draws MORE attention to the information it sets off, not less.
The meeting is scheduled for 1:00–2:00 PM.
She gave him her answer—a firm no.
