Introduction to Tag Questions

Tag questions (also called question tags) are short questions added to the end of statements to:

  • Seek confirmation (“It’s cold today, isn’t it?”)
  • Encourage agreement (“This cake is delicious, don’t you think?”)
  • Make polite requests (“You could help me, couldn’t you?”)

Basic Structure of Tag Questions

Formula:

Statement + comma + auxiliary verb + pronoun

Examples:

  1. “You’re coming to the party, aren’t you?”
  2. “She doesn’t live here anymore, does she?”
  3. “They’ve finished the project, haven’t they?”

Rules for Forming Tag Questions

1. Auxiliary Verb Matching

  • Use the same auxiliary verb as in the main statement
  • If no auxiliary, use “do/does/did”

Examples:

  • “He is French, isn’t he?”
  • “You like coffee, don’t you?”
  • “They went home, didn’t they?”

2. Positive/Negative Reversal

  • Positive statement → negative tag
  • Negative statement → positive tag

Examples:

  • “You know the answer, don’t you?” (positive → negative)
  • “She hasn’t called, has she?” (negative → positive)

3. Pronoun Agreement

  • Always use a pronoun that matches the subject

Examples:

  • “Mary is late, isn’t she?”
  • “The children are sleeping, aren’t they?”
  • “This book is interesting, isn’t it?”

Special Cases and Exceptions

1. “I am” → “aren’t I”

  • “I’m on time, aren’t I?” (never “amn’t I”)

2. Imperatives

  • Use “will you/would you” for commands
    • “Open the window, will you?”
  • Use “won’t you” for invitations
    • “Have some tea, won’t you?”

3. “Let’s” → “shall we”

  • “Let’s go to the beach, shall we?”

4. Negative Words

Words like “never”, “hardly”, “scarcely” make the statement negative:

  • “You never call me, do you?”

5. “There is/are”

  • “There’s a problem, isn’t there?”

Intonation Patterns

1. Rising Intonation (↗)

  • When genuinely unsure of the answer
  • “You live on Maple Street, don’t you?↗”

2. Falling Intonation (↘)

  • When expecting agreement
  • “Nice weather today, isn’t it?↘”

Common Mistakes to Avoid

  1. Mismatched auxiliary verbs:
    • Wrong: “She goes to school, isn’t she?”
    • Right: “She goes to school, doesn’t she?”
  2. Incorrect pronouns:
    • Wrong: “Everybody left, didn’t he?”
    • Right: “Everybody left, didn’t they?”
  3. Double negatives:
    • Wrong: “You don’t know, do not you?”
    • Right: “You don’t know, do you?”

Advanced Usage

1. Rhetorical Tags

Used to make pointed comments:

  • “So you broke the vase, did you?”

2. Sarcastic Tags

With opposite meaning through tone:

  • “Oh, you’re an expert now, are you?”

3. Encouraging Response

In conversations to keep them going:

  • “You’ve been to Japan, haven’t you?”

  2. Identify the mistakes:

    • Checking if a restaurant is still open
    • Confirming someone’s birthday

Real-World Applications

  1. Customer Service:
    • “You’d like the receipt in the bag, wouldn’t you?”
  2. Teaching:
    • “The past participle of ‘go’ is ‘gone’, isn’t it?”
