Punctuation Marks and Their Uses

Punctuation helps readers understand your writing by showing where to pause, what's important, and how ideas relate.

Commas

Commas signal a short pause. Use them to:

  • Separate items in a list: apples, bananas, and oranges
  • Join independent clauses with a conjunction: She was tired, but she kept going.
  • After an introductory clause: Although it rained, we played.

Apostrophes

Apostrophes have two jobs:

  1. Possession — add 's: the dog*'s** bowl*, James*'s** book*. For plurals ending in -s, just add ': the students*'** work*.
  2. Contraction — mark missing letters: do not → don*'t***, it is → it*'s***.

Semicolons

A semicolon (;) joins two closely related independent clauses without a conjunction:

  • She studied all night*;** she passed with distinction.*

Colons

A colon (:) introduces a list, explanation, or quotation:

  • She had one goal*:** to win.*
  • Bring the following*:** a pen, paper, and a ruler.*

Quotation Marks

Use quotation marks for direct speech and titles of short works:

  • She said, "Come here."
  • Put the comma or period inside the closing quotation mark.
