in/at the event

At is correct, but the sentence isn't. It would be "I saw her at an event".

Is it correct to say: "I saw at the party"

"I saw her at the wedding"

How is it different from

I saw her at the theater. Should it be "I saw her in the theater"

addyaddyIs it correct to say: "I saw at the party""I saw her at the wedding"How is it different fromI saw her at the theater. Should it be "I saw her in the theater"

The first two sentences are fine.

How is it different from I saw her in / at the theater?

When you say "I saw them in the threatre" it means that they are inside the theat

Is it correct to say, "I am at a meeting."

I have heard people use "in," not "at."

Please let me know.

Those are all correct!

Events like parties and weddings aren't a physical place; they're really just a gathering of people based on an idea. So it's "at" for those sentences. If you heard someone say "She was in the wedding", it would mean she was a participant, like a bridesmaid. It's similar to "I saw him in a play": it would mean the speaker saw an actor performing in a play.

Both can be correct, and are often used interchangably. I think that "in" has a stronger feeling of participation, the same as "in a wedding" or "in a play" both do.

Compered in an event or at an event.

Which would be the correct preposition?
