Questions & Answers about В магазине мы купили манго и киви для завтрака.

Why is it в магазине, not в магазин?

Because в магазине means in/at the store as a location, and after в when you are talking about location, Russian usually uses the prepositional case.

• магазин = store
• в магазине = in the store / at the store

Compare:

• в магазин = to the store (direction, motion)
• в магазине = in the store (location)

So in this sentence, the buying happened there, so в магазине is correct.

What case is магазине?

It is the prepositional case.

The noun магазин changes like this:

• nominative: магазин
• prepositional: в магазине

This is a very common pattern for masculine nouns after в or на when they describe location.

Why is мы used? I thought Russian often drops subject pronouns.
