Questions & Answers about Mein Cousin wohnt in einer anderen Stadt.
Why is it in einer and not in eine?
The preposition in is a two-way preposition. Because we are talking about a fixed location where someone already is (answering the question where?), it takes the dative case. If he were moving to another city, it would take the accusative case (in eine).
Why does the adjective anderen end in -en?
Because it is in the dative case. When an adjective comes after an article like einer in the dative case, it always takes the -en ending, regardless of the noun's gender.
What gender is the word Stadt?
It is feminine (die Stadt). We can see this in the sentence because the indefinite article changes to einer in the dative case, which is the specific form for feminine nouns.
Could I use lebt instead of wohnt in this sentence?
Yes, you can. wohnen specifically means to reside or dwell in a place, while leben is a broader word for being alive or living your life. When talking about the city or country you live in, both are correct and commonly used.
