Auxiliary verb "yao" and its multiple meanings

You probably already know the basic meaning of 要 (yào) as "to want." It is 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.

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. With that said, you definitely need to be aware of the different possible meanings listed above.
