Can you write a letter to / for me.

[Boris Tatarenko]

Hello.

What the difference between "Can you write a letter for me?" and "Can you write a letter to me?".
I do have a problem with "to" and "for".

Moreover, I mix up with sentences like "Oh my God! It's too hard for me" or "...It's too hard to me". And "English is an easy language for studying" or "to study".

As you can see, I'm absolutely zero.

Thanks in advance.

If I write a letter to you, I write a letter adressed to you. If I write a letter for you, I write a letter to someone on your behalf.

Bhai has answered your first question.

For your second sentence, I prefer "for me". Your third sentence uses the word "study", but I suspect you meant "learn". But in either case, I prefer the infinitive form.
