How do I say ‘really?’
The standard natural reaction when asking whether surprising information is true.
真的吗
Really? / Is that true?
LITERAL
Is it true?
WHAT IT REALLY MEANS
Really? / Is that true?
WHEN IT FITS
Reacting to newsConfirming surprising informationBoth speech and messages
A short 真的？ is common among friends, while 是吗 can be calmer and less emotionally marked.
真的吗 directly questions truth value — it is neutral in itself, but repeating it insistently (真的吗？真的？) shifts the tone from surprised to skeptical. 是吗 (“is that so?”) is the lighter alternative: it acknowledges the information without the emotional weight of questioning its veracity. In text messages, 真的？ (without 吗) is the standard clipped casual form among friends.
