It frequently appears in sentences ending with particles like 㗎 or 喎 to emphasize the speaker's surprise or questioning tone regarding a deviation from the norm.

Examples

Logically speaking, he should have returned home by now.
Logically speaking, this shouldn't have happened.

Common phrases

Common mistake
