How it's used

Use this to signal that a statement is based on logic or models rather than real world evidence. It often acts as a polite preface to a 'but' clause, signaling that the speaker is about to introduce a practical complication. It is frequently paired with 實際上 to create a sharp contrast between abstract possibility and concrete reality.

Common mistake

Avoid using this to describe something that is definitely true. It implies a degree of detachment from reality, so using it for a simple fact can sound overly academic or noncommittal.
