Because; since; used to introduce a reason.

How it's used

Functions as a causal conjunction that sounds slightly more conversational and explanatory than the standard 因為. It often introduces a reason that the listener might not be aware of, acting as a bridge to provide context for a previous statement. It is particularly common in spoken explanations where the speaker wants to justify their actions or clarify a situation.

Examples

ngo5我m4唔heoi3去laa1啦，si6事gwaan1關gam1今jat6日hou2好攰。

I am not going, because I am very tired today.

Why aren't you eating? Is it because you are feeling unwell?

Common phrases

of great importance

Common mistake

Avoid using it in formal writing or professional reports, as it carries a distinctly casual, spoken tone. It is also less common to use it at the very beginning of a sentence compared to because in English; it usually follows the main clause.
