Definition

1. Interjection / Particle:
   • Yes, of course! / But yes!: A strong, emphatic affirmation used to contradict a negative question or statement. It asserts that something is true or will happen, contrary to the negative assumption implied.
   • Of course there is! / Of course I do!: Used to confirm the existence of something or the truth of a statement that was questioned in a negative form.

Usage Examples

• Interjection / Particle:
  • "Anh không thích cà phê ư?" - "Có chứ!" ("You don't like coffee?" - "Yes, of course I do!")
  • "Ở đây không có wifi à?" - "Có chứ!" ("There's no wifi here?" - "Of course there is!")
  • "Cô ấy sẽ không đồng ý đâu." - "Có chứ, cô ấy sẽ đồng ý." ("She won't agree." - "Yes she will, she will agree.")

Advanced Usage

• The phrase "có chứ" is primarily used in spoken, conversational Vietnamese. Its function is entirely reactive, depending on a preceding negative question or assumption. It carries a tone of slight surprise or insistence that the other person is wrong to doubt.
• It can be followed by a repeated or clarified statement for emphasis.
  • "Có chứ, tôi rất muốn đi." ("Yes, of course, I really want to go.")

Variants and Related Words

• Có: The standard, non-emphatic word for "yes" or "to have." "Có chứ" adds strong emphasis and contradiction.
• Dĩ nhiên: Means "of course" or "naturally." It is a calmer, more logical affirmation than the reactive "có chứ."
• Tất nhiên: Similar to "dĩ nhiên," meaning "certainly" or "of course."

Synonyms

• Certainly: Used to emphasize that something is true.
• Of course: Used to give or emphasize agreement.
• But yes!: Used to strongly affirm after a negative suggestion.
