How it's used
Functions metaphorically to describe any situation where the outcome is unpredictable or undecided. It carries a slightly formal or analytical tone compared to simply saying 唔知, making it common in news reports, office discussions, or when speculating about future events. It is almost always preceded by 係一個 to emphasize the state of uncertainty.

Common mistake
Do not use this to describe a person who is unknown or a stranger, as it strictly refers to abstract situations or mathematical values. For a person you do not know, use 陌生人 instead.
