Where do we use at?

Today let’s take a look at the preposition at.

We use at in the following cases:

1) Exact time

If you want to meet with someone, when you decide the time you’ll meet you say: “I’ll meet you at half past 8“. At is also used with night.

I'll call you at night.
I can’t talk right now. I’ll call you at night.

2) Specific location

If I wanted to say which university I studied at, I’d say that I studied at Dnipropetrovsk National University. Or, if my friend works in a bank and we both know what bank it is, I can say that She works at the bank next to my house.
Notice that I used the to show that we both know what we’re talking about.

Let me point out that when you talk about what’s happening inside a building, you need to use the preposition in.

3) Indicating contact information

When you want to provide someone with your phone number, e-mail address or your website, you can use at with reach. This is a formal way of giving your contact information.

I can be reached at eugene@email.com

Sorry for the fake address, but I wouldn’t want to get a lot of spam on my real addresses. 🙂

4) Events

At a concert.
I met one of my friends at a concert.

The concert, in this case, or a party is an event that takes place somewhere and, hence, we use at with these.

5) Unique places

This is similar to №2. When you want to tell people that you are in your house, your workplace, that you did something in your university, you use at to point it out.

Doesn’t seem too hard now, does it?
Let’s try practicing it in context:

I hope you found it useful to you and, as usual, I’ll see you at the weekend. 😉
