“What's the point of this meeting anyway?”
You have a meeting that was scheduled at work. You don't know what the meeting is for. You are frustrated because your department often has long meetings that seem unimportant to you. You ask this of a coworker who's a close friend of yours.
What's the point of this meeting anyway?
"The point" of something is the reason for doing it. But this word is often used in the negative sense: "what's the point?", "there's no point", "I don't see the point", etc.
You can say "What's the point of (something)?" or "What's the point of (doing something)?":
What's the point of Facebook? I don't get it.
What's the point of studying math in school anyway? No one ever uses it in real life.
When you ask "what's the point of ___?" it's usually a criticism and can sound negative. So you should use it when you are angry and annoyed about something. Depending on your personality, you may not want to show people that you're angry unless you're close to them. A more polite way to ask "What's the point of this meeting?" would be:
"What's this meeting about?"
English speakers sometimes add "anyway" to the end of a question like this:
Where are we going anyway?
Adding "anyway" suggests that you're a little bit annoyed. It's like saying "I don't like (something). Also, I have a question about it." For example, if you're frustrated about a difficult homework assignment, you can ask:
This assignment is so annoying. Why are we studying this anyway?
