The Genitive Plural of Nouns
Родительный падеж имён существительных (мн.ч.)
1) The genitive case of a noun denotes possession and answers
the questions чей? чья? чьё? чьи? (whose?), кого? (of whom?), чего? (of what?)
Чьи книги? - Книги студентов.
2) The genitive is used after the words нет (have no; there is no), не было (had no; there was no),
