When we talk about someone’s abilities, we will use the word “nang4” (能) to express one can do something. On the contrary, we use the word “bat1 nang4” (不能) to express one cannot do something in one’s ability.

The question form: When we ask the questions about abilities, we will use the words “nang4”
(能) and “bat1 nang4” (不能) to form the question.

Question pattern: Subject + “nang4” (能) + verb + “maa1” (嗎)? Or Subject + “nang4 bat1 nang4” (能不能) + verb?
