Punctuation Rules

Punctuation rules are the guidelines that dictate how punctuation marks are used in writing to clarify meaning and ensure readability.

They help structure sentences, indicate pauses, and connect ideas, making the text easier to understand.

The Basics of Punctuation

Punctuation marks structure your sentences and make your writing understandable.

They indicate pauses, stops, and the relationships between ideas. Without punctuation, writing would be a jumble of words with no clear meaning.

Common Punctuation Marks and Their Uses

Periods (.)

  • Use periods to end declarative sentences. Example: The meeting is at 3 PM.

  • Use periods in abbreviations. Example: Dr. Smith will see you now.

Commas (,)

  • Use commas to list items. Example: We bought apples, oranges, and bananas.

  • Separate clauses in a sentence. Example: When it rains, we stay indoors.
