要 (yào) and 想 (xiǎng)
Instead of using 要 (yào) it is also possible to use the word 想 (xiǎng). These two words are both auxiliary verbs and are largely interchangeable, and both generally mean "to want." The only difference worth mentioning is that 要 (yào) is often used when it is something you want to/need to do, and plan to take action on. It can sound a bit more demanding (and less polite). 想 (xiǎng) on the other hand, is often conveys an idea on one's mind, that one may or may not take action on. You can think of it as meaning "would like to."
- 我 要 喝 咖啡 。 I am going to get my hands on some coffeeI want to drink coffee.
- 我 想 喝 咖啡 。 I want to drink a cup of coffee, but may or may not act on thatI'd like to drink coffee.
