we vs us

We is a pronoun used as the subject of a verb, to mean the person communicating and at least one other person.

We can be inclusive:-

For example:-

"We need to get to the airport!"

Or exclusive:-

For example:-

"We need to get to the airport! Will you take us?"

Us is also a pronoun, but it is used as the object of a verb or a preposition to mean the person communicating and at least one other person.

For example:-

"Thank you for taking us to the airport."

In the UK we often use it to refer to a large group of people that includes the person communicating.

For example:-

"Us Brits have to stick together."

Many linguists will argue that it should be "We Brits", as in "We few, we happy few..." (thanks Shakespeare), and they have a point, but when we say "us" we sort of mean "all of us".

!Note - in the UK "us" is also a very informal way of saying "me".

For example:-

"Give us a gummy bear."
