Questions & Answers about sensei wa watashi ni atarashii jisho o kudasaimashita.
は marks 先生 as the topic of the sentence.
So 先生は means as for the teacher or the teacher, ....
In this sentence, the teacher is the person the sentence is mainly about. Japanese often organizes information by topic first, rather than by subject in the same way English does.
- 先生は = as for the teacher
- 私に = to me
- 新しい辞書を = a new dictionary
- くださいました = gave (to me/us), respectfully
So the structure is something like:
As for the teacher, to me, a new dictionary gave.
That sounds strange in English, but it is normal in Japanese.
に marks the recipient here—the person who received something.
So:
- 私に = to me
In giving/receiving sentences, に often shows who receives the item.
Examples:
- 先生は私に本をくれました。 = The teacher gave me a book.
- 友だちは弟にお菓子をあげました。 = My friend gave sweets to my younger brother.
In your sentence, 私 is the receiver, so に is used.
