How it is used
- The rising tone (ó) here marks a questioning "oh?" or "really?", used when checking or mildly doubting what was just said.
- This differs from the falling-tone 哦 (ò), which signals realization, "oh, I see", after learning something new.
- As a bare, flat-toned reply in texting, 哦 can sound cold or dismissive, so tone/context matters a lot.
- Pure interjection, never a content word, never takes an object.
