The difference between AT and IN

by Ravindar
(Singapore)

I have one question. Sometimes when I speak I wonder how can I can know when to put the correct word of use "AT" " and or "IN".

I am in the class,
I am at the factory,
I am at the bank,
He is at home...etc

Thanks for your continious continuous posting Diana.

Hi Ravindar,

Thanks for asking! This is not a silly question. Many people find prepositions difficult. Regarding the difference between AT and IN, here is a general explanation.

You probably already know that both AT and IN are used to describe position, but there are some differences.

Here are some rules;

AT

-AT describes position at a specific point.
It's very cold at the bottom of the ocean.

-AT is also used with a larger place (a store, bank, airport etc)
Let's meet at the bank

-AT is used before the names of group activities at a party, at a meeting, at a play, at a parade

IN

-IN refers to position within large areas or in spaces that surround something on all sides
My keys are in my bag. He is not in his office. The car is in the garage

---

ON (I added this one too!)

-ON is used as "attached to" or wearing
Which finger do you wear your ring on?

-ON also refers to the surface of something
My computer is on my desk. The book is on the shelf
