When we use a preposition 'at' and 'in'?

[Guruh]

Dear Teacher,

What is the difference a preposition 'at' and 'in' ?
When we can use it?
Can you give me some example please?

Thanks,

Warm regard

'At' is a point location; 'in' is a 2- or 3-dimensional location. It often depends on the speaker's perspective.

We landed at LAX airport. -- a point in Los Angeles, or one of many airport 'points' around the world.
I got lost in LAX airport.-- within the structure or area.

Dear Mister Micawber,

Sorry Sir I'm still don't understand.

If I have an exercise like this

Fill in the blanks with the prepositions "in", "at" :

I was born ...... Singosari, a small town in East Java, but now I live ...... Jakarta.

My answer :
I was born at Singosari, a small town in East Java, but now I live in Jakarta. --> is this a correct answer ?

[Mister Micawber]

No-- 'in' and 'in'. With those kinds of verbs, you can imagine that the person is within the city.

Dear Mister Micawber,

thanks for your reply and patience to teach me

I see, how about the preposition 'at' sir. I still don't understand. The meaning 2 or 3 dimensional location?

Hi Guruh,

Generally you can say that 'at' is less precise than 'in' when you are talking about location. Consider 'at school' (studying) and 'in school' (physically present there).

Hi Mr Alan,

Thanks for your explanation. :)

Dear Mr. Micauber,

You said - "At" is a point location; "in" is ..etc.

Why have you used ; and not, after location. What is the difference better , and ; and how do we use them differently? I see ; sign often when I read English text, but I cannot differentiate between the 2. The ; and ,

Thank you in advance.

Acha.

Hello Acha,

I'm not quite sure what you are asking, but a semicolon (except when used in making lists) is used just as a period (full stop) is: to separate independent clauses. A comma has many uses, but cannot be used to separate independent clauses unless it is succeeded immediately by a coordinating conjunctiion (and, or, but).

Does that help?

I am not sure if I got them. Can you please give me an example of 2 sentences in which we use two different signs. The semicolon (;) and comma (,) signs.

Thank you.

Acha.
