How it's used
Often used to describe life milestones like marriage or graduation, which are referred to as 人生大事. While it can mean a serious issue, it is frequently used in a slightly hyperbolic way to emphasize the significance of an event in a conversation. It carries a heavier weight than just saying 緊要事.

Common mistake
Do not confuse this with 唔係大事, which is a common way to say something is not a big deal or no problem at all. Learners sometimes mistakenly use it to describe a big object, but it strictly refers to events or matters, not physical size.
