How it's used

While 為甚麼 is technically correct in written Chinese, it is almost never used in spoken Cantonese. Native speakers use 點解 in virtually every context, whether formal or casual. Using 為甚麼 in conversation sounds like reading from a textbook or speaking with a heavy Mandarin accent.

Common phrases

Common mistake

Learners often use 為甚麼 because they see it in dictionaries, but it sounds unnatural and stiff in speech. Stick to 點解 to sound like a local.
