Breakdown of Трек-номер и код товара указаны правильно.
Questions & Answers about Трек-номер и код товара указаны правильно.
Because there are two separate things being talked about:
- трек-номер = tracking number
- код товара = product code
They are joined by и = and, so together they form a compound subject. In Russian, a compound subject with и normally takes a plural predicate:
- Трек-номер и код товара указаны... = The tracking number and the product code are indicated...
So even though each noun is singular by itself, the verb form is plural because the meaning is they.
Указаны is a short passive participle, plural form, from the verb указать.
In this sentence, it means something like:
- have been indicated
- are listed
- are specified
So the sentence is literally close to:
- The tracking number and the product code are indicated correctly.
This kind of form is very common in Russian for stating a result or condition.
Compare:
- Адрес указан правильно. = The address is indicated correctly.
- Данные указаны неверно. = The data are indicated incorrectly.
