How it's used
This term functions as an emphatic way to state that something is inevitable or logically certain. It carries a stronger sense of deduction or necessity than simply using 實係 or 一定係. It is frequently used when the speaker is drawing a firm conclusion based on observed evidence.

Common mistake
Learners often confuse this with the Mandarin structure 是必, which is not used in the same way. In Cantonese, it is almost always used in the form 係必 to maintain the natural flow of spoken speech.
