“Would you like to go see a movie together sometime?”
There's a guy in one of your classes who you like. You've spoken with him several times, and you think you'd like to go out on a date with him. After a few minutes of conversation, you ask him this question.
Would you like to go see a movie together sometime?
In casual speech, you say "go (do something)" to mean "go (somewhere) and (do something)". For example:
Do you want to go see a movie?
This means to go to a movie theater and watch a movie.
Could you go find me a screwdriver somewhere?
This means to go to the place where tools are kept and find a screwdriver for the speaker to use.
This is a phrase to use when you want to ask someone out on a date.
Of course, you don't just come out with this at the beginning of your conversation. You have to make small talk with them and maybe tell them some interesting stories about yourself first. Then you can make the invitation using this phrase.
If you want to invite someone to hang out with you, but you don't specifically want to make it a date, you have to use a more indirect method of asking. For example:
Have you seen that new movie Walking the Tracks? I was thinking of going to see it. You want to go with me?
Me and some friends of mine are going out to this bar on Fifth Street tonight. You're welcome to join us if you'd like.
It can be confusing to try to figure out when to use "see" and when to use "watch". The first thing to remember is that they mean nearly the same thing. So even if you use the wrong one, you'll still be able to get your meaning across. It might sound a little funny, but it's no big deal. That having been said, here are the differences:
You can "see" things without trying, but "watching" something seems a little more active. For example, if you're outside at night and you think you see something moving, you say:
Did you see that?
You couldn't use "watch" in this situation. But here's an example where you should use "watch" instead of "see":
Sometimes I love to just sit on a park bench and watch people walk by.
For movies, TV shows, plays, and sporting events, "watch" is the most common verb:
A: What do you want to do?
B: Want to watch a movie?
I don't like to just sit at home and watch TV. I have to get out and do something productive on the weekend.
However, when you're talking about going out to a theater or a movie theater, it's common to use "see". This is why the example at top uses "see a movie". Here's another example:
I'm planning on seeing Pirates of the Caribbean 4 the first day it comes out.
"Watch" is still OK for describing this activity, but it's less common.
It's also more common to use "saw" or "seen" when you're describing movies or TV shows that you've experienced in the past:
Have you seen Toy Story 3?
I haven't seen it. Is it any good?
"Watch" is not incorrect in this situation; it just emphasizes the actual action of watching:
I watched Toy Story 3 with my kids last night. They were into it at first, but then one of them fell asleep halfway through.
