WHAT IS THE DIFFERENCE BETWEEN 'IN' AND 'AT'...?

Seems to be similar in many situations, doesn't it? Yes, each may be replaced at many situations on focusing the place where the event happens.

Both are prepositions - is well known. But their usage differs with each other.

I AM IN NAGAPATTINAM

I AM AT NAGAPATTINAM

Both of them are right but slightly differ. What does it differ..?

If the guy stays there permanently, the first is right while the second means the he stays for sometimes. After an hour he might shift his place to Thiruvarur, because he is a medical rep.

YES, HE IS AT HOME, YOU MAY COME AND MEET HIM

YES, HE IS IN HOME, YOU MAY COME AND MEET HIM

Though grammatically both are right, in this situation, the second is right because it's nothing surprise if he leaves home thereafter.

----------------------------------------------------------------

The one more big matter in this regard. AT is majored comparing to IN, as IN can be replaced by AT at many times particularly pointing out the place of action.

But when to mean the time of an action, only AT is used.

I'LL BE THERE AT 9 PM. (but not in 9 PM)

AT WHAT TIME DID YOU WAKE UP TODAY? (but not "in what time")

------------------------------------------------------------------

Another one main usage there in English for AT

HE SHOUTED AT HIM SO LOUDLY.

YOUR DOG ALWAYS BARKS AT ME.

WHY ARE YOU LAUGHING AT ME?

----------------------------------------------------------------

IN can also be used as an adverb besides a preposition

THE DOCTOR IS IN.

WHEN YOU HAD BEEN THERE WHO WAS IN?
