How it's used
This is a formal idiom that sounds quite heavy and dramatic in everyday speech. It is often used to emphasize the gravity of a situation when someone is being too casual or irresponsible. Because it carries a literary weight, using it in a lighthearted context can sound sarcastic or overly theatrical.
Examples
This matter is very serious, don't mess around.
Do you think this matter is of great importance?

Common phrases
This is a serious matter, caution is paramount.
Common mistake
Learners often mistake this for a standard adjective, but it functions as a complete clause or a predicate. It cannot be modified by degree adverbs like 好 or 幾, so saying 幾茲事體大 is grammatically incorrect.
