The reason is because...
colloquialcommunication
How it's used
This phrase is a direct translation of the English structure 'the reason is because', which is often considered redundant in formal writing. In Cantonese, it is used frequently in speech to emphasize the cause of a situation. It functions as a connector that bridges a subject with its explanation.
Examples
The reason he is late is because of traffic.
Do you know what the reason is?

Common phrases
the reason is because of that
Common mistake
While common in speech, it is technically tautological because the word 原因 already implies the cause. Using it in formal written reports or academic essays is often discouraged by teachers who prefer a more concise structure like 係因為 or 原因係.
