"Is that so?" is how you ask if something is true in English.
For example, if someone tells you a story and you want to confirm if it's accurate, you can say "Is that so?" followed by the story.
This phrase is often used to show surprise or di***elief at the information given. It can also be used to seek clarification or more information.
Here's an example of how to use it:
Person A: "I just got promoted at work!"
Person B: "Is that so? That's amazing!"
In this case, Person B is showing surprise and admiration for the promotion.
Remember, when using this phrase, it's important to maintain a neutral tone, as it can come across as dismissive or rude if used incorrectly. So, use it appropriately and respectfully to avoid misunderstandings.
