“Is that so?” is a common English expression used to express surprise, disbelief, or to invite the speaker to continue with their story. It’s similar to saying, “Really?” or “Oh, is that the case?”
Here are two examples in sentences:
Example 1:
Upon hearing that her friend won a lottery, Emily exclaimed, “Is that so?”
Example 2:
When Jim heard about the new restaurant downtown from his coworker, he responded with, “Is that so? I’ll have to check it out!”
Now let’s see it in conversation:
Example 3:
Alice: I heard that our team won the game last night.
Bob: Is that so? I missed it!
Example 4:
Kevin: They say it’s going to rain all week.
Rachel: Is that so? I better get my umbrella ready then.
When you hear someone say, “Is that so?“, they are expressing interest in what you’re saying, and they are likely inviting you to share more details. It’s a casual phrase that can be used in many different social situations.
