Questions & Answers about Это подделка, упаковка которой такая же, как наша.
Why do we use такая же here instead of the standard form такой же or так же?
The phrase такой же ... как acts like an adjective, so it must match the noun it describes in gender, number, and case. Here, it describes упаковка (packaging), which is a feminine noun in the nominative case. Therefore, we use the feminine form такая же. If we were comparing adverbs or actions instead of nouns, we would use так же.
Why is it которой? Doesn't that word usually mean 'which' or 'who'?
It does, but here it is in the genitive case. Которой literally means 'of which'. Together, упаковка которой translates to 'the packaging of which' or 'whose packaging'. We use the feminine genitive form here because it points back to the feminine noun подделка (fake).
Why is the word order упаковка которой instead of которой упаковка like we say 'whose packaging' in English?
When using the genitive form of который to mean 'whose', Russian typically places it right after the noun it belongs to. While которой упаковка would be understood, упаковка которой is the standard and most natural word order.
Why does the sentence end with наша and not a different case like нашу?
