Questions & Answers about Мне не нужен такой подарок.
Because Russian expresses this idea differently from English.
In English, we say I don’t need this kind of gift, with I as the subject.
In Russian, the structure is closer to:
To me, such a gift is not needed.
So:
- мне = to me (dative case)
- подарок = the thing that is or is not needed
That is why мне is used instead of я.
Нужен means needed or necessary.
It comes from нужный (necessary / needed), but here it appears in the short form, which is very common in sentences like this.
So Мне не нужен такой подарок literally means:
Such a gift is not needed to me.
In natural English, that becomes:
I don’t need such a gift or I don’t want a gift like that (depending on context).
