How it's used

Functions as a formal marker to indicate that an item belongs to a larger group. While widely understood and used in speech, it carries a slightly more structured or academic tone compared to purely colloquial phrasing. It is almost always placed at the end of a noun phrase to define the scope of the group.

Common mistake

Learners often try to use it like the English word 'one' in isolation, but it must be preceded by a noun phrase describing the group. You cannot simply say '呢個係之一' to mean 'this is one', as it requires the context of the group it belongs to.
