English Grammar: Punctuation Rules

For Indian Hindi Medium Students — Beginner to Advanced

1. Full Stop / Period (.)

When to use:

• At the end of a complete sentence
• To show the sentence is finished

Examples:

Hindi understanding:

• जब sentence पूरा हो जाए, तो (.) लगाते हैं
• इसे “पूर्ण विराम” कहते हैं

Advanced:

• Also used in abbreviations
  • Mr. Singh (Mister)
  • Dr. Sharma (Doctor)
  • U.S.A. (United States of America)

2. Comma (,)

When to use:

A) In a list (items)

• I like apples**,** oranges**,** and bananas.
• We need a pen**,** notebook**,** and pencil.
• She visited Delhi**,** Mumbai**,** and Bangalore.

B) After introductory words/phrases

• After dinner, we went out.
• In the morning, I exercise.
• However, he was late.
• First, do your homework.

C) Before FANBOYS in compound sentences

• I wanted to go**,** but it was late.

• We can stay**,** or we can leave.

D) Before and after extra information in a sentence

• My teacher**,** Mr. Sharma**,** is very kind.

E) After direct address (when calling someone)

• Friends, please listen to me.

F) In dialogue/speech

• “Wait here**,” he said,** “I’ll be back soon.”

Examples:

• Yesterday, I met my old friend.
• She is smart**,** yet she is humble.

Hindi understanding:

• जब list हो, तो (,) लगाते हैं
• Introductory phrase के बाद (,) लगता है
• Compound sentence में दूसरे clause से पहले (,) लगता है

Pro tip:

• “Oxford comma” = List में आखिरी item से पहले भी (,) लगाते हैं (अधिकतर अमेरिकी English में)

3. Semicolon (;)

When to use:

A) Join two closely related independent clauses

• He loves reading; his sister prefers sports.
• I was hungry; I ordered food.
• She passed the exam; she felt proud.

B) In complex lists (where commas already exist)

• We need apples, oranges**;** milk, butter**;** and bread, eggs.

Examples:

• The weather was cold**;** we stayed inside.
• He worked hard**;** he achieved success.

Hindi understanding:

• Full stop (.) से कम stop है
• दोनों clauses बहुत closely related होनी चाहिए
• Pause बहुत ज़्यादा नहीं होता

Remember:

• After semicolon, new clause का first letter capital नहीं होता (usually)
• He is smart**;** he works hard. ✓
• He is smart**;** He works hard. ✗ (mostly wrong)

4. Colon (:)

When to use:

A) Before a list

• Ratio**:** 2**:**5
• Title**:** Grammar Rules

Examples:

• I have a dream**:** to become a doctor.
• You need these subjects**:** English, Hindi, and Maths.

Hindi understanding:

• अगर list या explanation दे रहे हो, तो (:) लगाते हैं
• यह एक “pause” है जो अधिक information देने वाली हो

Types of questions:

• Yes/No questions: Do you play cricket?

Hindi understanding:

• जब सवाल पूछें, तो (?) लगाते हैं
• “प्रश्नवाचक चिह्न” कहलाता है

Important:

• Question के अंदर comma न लगाएं
• What is your name**?** ✓
• What is your name**,?** ✗
