How it's used
Used primarily in formal contexts, such as legal, academic, or professional settings, to introduce a logical basis or justification for a decision. It sounds significantly more stiff and official than the common spoken alternative 係因為. It is rarely used in casual conversation between friends, where people would prefer to use 睇住 or 因為 instead.

Common mistake
Learners often overuse this in casual speech where it sounds overly formal or robotic. It is not a direct substitute for because in everyday sentences like I am late because of traffic.
