Auxiliary verb "yao" and its multiple meanings

You probably already know the basic meaning of 要 (yào): "to want." It's actually a quite versatile word, though, and can also take on the meanings of "to need" as well as "will (do something)." In every case, context is crucial for figuring out which meaning someone is trying to express.

要 as "want"

This structure could be used ordering food in a restaurant or a shop.

Structure

Subject + 要 + Noun

Examples

• 我 要 一 杯 水。
• 我 要 一 份 牛排。
• 我 要 一 杯 咖啡。
• 我 要 一 个 面包。
• 我 要 冰 的 可乐。
• 你 要 热 牛奶 吗？
• 我 要 一点 糖。
• 我 要 两 份 鸡 肉。
• 我 要 法国 红 酒。
• 我 要 苹果 汁。

要 as "want to"

In Chinese, 要 (yào), the verb "to want" doesn't quite function like the English. It means "want to" (similar to 想), but its tone is quite firm.

Structure

Subject + 要 + Verb

Examples

• 我 要 吃 巧克力。 I want to eat chocolate.
• 我 要 跟 你 一起 去。 I want to go with you.
• 我 要 吃 西餐。I want to eat western food.
• 我 要 学 中文。I want to study Chinese.
• 我 要 去 泰国。I want to go to Thailand.
• 我 要 买 一 个 新 手机。I want to buy a new cell phone.
• 我 要 工作。I want to work.
• 我 要 打 电话。
• 我 要 见 他。
• 我 要 试 一下。

当然，你可以用“想要”表示“want to"。这样的话，句子的语气就没有“要”那么强烈了。

要 as "need to"

If you crank the urgency of "to want" up a few notches, you get "to need." The two meanings overlap, creating a fuzzy, "needy" gray area.

Context, context, context

You may have noticed that the meanings can easily overlap. To figure out what is intended, you need to use context. How urgent is the situation? Is it likely to be something the speaker really wants to do? Is it something that's totally going to happen, regardless of anyone's preferences? Most often, a little background knowledge and some common sense are all you need to figure it out. But you definitely need to be aware of the three possible meanings listed above.
