I wrote for my mother a letter.

This is wrong.
Your post is confusing.
If your mother cannot write, it should be:- "I wrote a letter for my mother"
If you intend to send the letter to your mother, it should be:- "I wrote a letter to my mother"
Is that easier?
foxfirebrand said:If you think in terms of formal grammar, it might be helpful to point out that in "I wrote my mother a letter, " letter is the direct object (what you wrote) and mother is the indirect object (to whom you wrote). The direct object is like the accusative case, and the indirect object is the dative.
