My life My stories: Differences between in and at.

Hello there... Today post is a little bit of education in English language. Although you may know this but it is for enhancement only. I usually said and post "I am in Tamparuli" not "I am at Tamparuli" in any conversation whether in text or verbal communication. Did you know that this two phrases is correct but it may depending upon the context of the conversation. In - is a general explanation and At - is a specific explanation. Usually in and at is use to show the location of a person, events, animal and thing. So which phrases is true " I am in Tamparuli or I am at Tamparuli"? For me I will use I am in Tamparuli, but if I went to State Library in Tamparuli, I will use I am at the State Library of Tamparuli. I hope this information can help you guys.

More explanation about In and At:

1. By looking at the dictionary we get:

at: In or near the area occupied by; in or near the location of

in: Within the limits, bounds, or area of

People are usually using in to note a general location and at for a more specific location.

I'm in the building, at the front desk

I'm in New York, at the conference

I'm in New York, at the Empire State Building

Extra note: also the difference when in is used to indicate inside

I'm in the elevator = I'm inside the elevator

I'm at the elevator = I'm near the elevator

2. Something missing from the other answers posted so far, I feel, is that at is appropriate where there is an expectation of or potential for travel away from the location, or where it's important to distinguish it from other potential locations. So if somebody asked where I was, I might say

I'm at the house

if I'd been at other locations that day and expected only to be there for a while (especially if the other person knew this). Similarly, I might say

I'm at the hotel.

For slightly different reasons, I'd say

I'm at the Hilton Hotel

to distinguish it from the other potential hotels.

In the house or hotel is more appropriate in other contexts but I"m not going to examine those exhaustively right now.

3. The most suitable explanation:

When talking about location, in is generally used for a larger area where there are numerous specific locations possible

I am in the United States.

I am in New York.

I am in the Chelsea neighborhood.

I am in my backyard.

The preposition at is generally used for a specific location or thing.

I am at the intersection of Hollywood and Vine [streets].

I am at the Empire State Building.

I am at my hotel.

I am at home.

I am at the old oak tree in my yard.

However, the above at usage is indifferent to whether you are indoors or outdoors. You could be on the street in front of your hotel or inside. You could be in your yard at home or in the bathroom at home.

If you want to convey that you are indoors at a specific location, you would use in

I am in the Empire State Building.

I am in my hotel.

I am in my home.

The above conventions reflect an American usage which may or may not be similar in other English speaking countries.
