Scene — a rainy breakfast
Rain has followed Maya down Banyan Lane and into the breakfast shop. Auntie Lin notices that she is late, then asks what brought her to Taipei in the first place.
A-Li is nearby on his two stools, with an unfinished soy milk beside his egg pancake. He has a question about Maya's order, too.

Learn — ask why and give a reason
Start with a short question, then listen for the difference between a reason and its result. The longer lines help Maya explain both her move and her late arrival.
Say each line aloud before moving on.

為什麼?
Why?
When to use it: Ask this when you want someone to explain a choice or situation.
You can use this short question on its own when the topic is already clear.
Say it: The last syllable has a neutral tone.

因為我沒帶傘
Because I didn't bring an umbrella.
When to use it: Give this reason when forgetting your umbrella affected your plans.
Use 沒 for something you did not do, such as bringing an umbrella.

所以我才來晚了
That's why I'm late.
When to use it: Say this after explaining the reason you arrived late.
才 points back to the reason and emphasizes why the lateness happened.

我是因為想練習中文
It's because I want to practise Chinese.
When to use it: Explain your own reason for coming somewhere or doing something.
Here, 是 puts extra focus on your reason.

你怎麼會決定搬來臺北?
How did you decide to move to Taipei?
When to use it: Ask someone what led them to make the decision to move to Taipei.
怎麼會 asks how something came about, rather than asking for a step-by-step method.

主要原因是工作
The main reason is work.
When to use it: Name work as your most important reason without ruling out other reasons.
主要 leaves room for other reasons besides the one you name.
