Questions & Answers about Страна происхождения указана в таможенной декларации.

Why is it страна происхождения and not some other case combination?

Because страна is the main noun, so it appears in the nominative singular: страна.

The word происхождения is in the genitive singular because Russian often uses the pattern:

• noun + genitive noun

to express something like X of Y.

So:

• страна происхождения = country of origin
• literally: country of origin/of coming from

This is a standard Russian noun phrase, especially in formal or official language.

What case is происхождения, and why?

Происхождения is genitive singular.

Its dictionary form is происхождение. Here it changes to происхождения because it depends on страна and specifies what kind of country it is:

• страна происхождения = country of origin

This is similar to other Russian expressions like:

• центр города = city center
• номер паспорта = passport number
• дата рождения = date of birth

So the genitive here is not showing possession in the narrow English sense; it is just a very common way to connect nouns.

Why is it указана and not указан or указано?
