Negate 有 (yǒu) with 沒 (méi)
To talk about “not having” something, you negate the word 有 (yǒu) with 沒 (méi). Remember this important point: if you negate 有, always use 沒. The two words go together.
Examples:
我沒有車。
Wǒ méiyǒu chē.
I don't have a car.
他們沒有錢。
Tāmen méiyǒu qián.
They don't have money.
他沒有學位。
Tā méiyǒu xuéwèi.
He doesn't have a degree.
That’s how you negate 有. But there’s a different word for everything else!
