How it's used
While 重大 is understood in Cantonese, it leans towards a formal or written register. In casual speech, native speakers often prefer using 好重要 or 緊要 to convey the same sense of significance or urgency. Using 重大 in everyday conversation can make you sound like you are reading from a news report or a formal document.
Examples
This matter is very significant, you cannot decide it casually.
Did they make a major discovery?

Common phrases

major responsibility
Common mistake
Learners often overuse 重大 in contexts where it sounds overly dramatic or stiff. For routine importance, stick to 重要, reserving 重大 for events or consequences that are truly consequential or life-changing.
