Punctuation Marks in English Grammar – 13 Rules, Examples & Exercises

What is Punctuation?

Punctuation refers to symbols or marks used in writing to separate sentences, clarify meaning, and convey tone or pauses. It helps make your writing clear, organized, and easy to understand.

Punctuation marks may be small, but they hold great power. With the right punctuation, your writing becomes clear, professional, and meaningful. Practice regularly and always proofread your writing!

Why is Punctuation Important?

• Prevents confusion
• Shows where sentences start and end
• Adds emotion, rhythm, and tone
• Essential for writing emails, essays, reports, and formal documents

Without punctuation:

Let’s eat Grandma. (चलो दादी खाना खाते हैं.)

With punctuation:

Let’s eat, Grandma. (चलो खाना खाते हैं, दादी.)

Big difference, right?
