Learn Hardcore Russian: У меня есть разные книги.

In Russian, possession is normally shown by the existential construction У + genitive (the possessor) + есть + nominative (the thing possessed). Literally, У меня есть means “At me there is,” but idiomatically it translates as “I have.” The verb иметь (“to have”) exists in Russian, but it's formal or literary and rarely used in everyday speech.

What is the grammatical role of есть in this sentence, and can I omit it?

Here, есть is the existential verb “to be,” indicating that something exists or is present. In casual speech, Russians sometimes drop есть when talking about permanent facts or relationships (e.g., У меня папа врач – “My dad is a doctor”). However, in statements of simple possession—especially when you want to sound clear and neutral—you usually keep есть. Without it, У меня разные книги sounds incomplete or stylistically odd for just saying “I have various books.”

Which case and number is книги, and how do I know?

In У меня есть разные книги, книги is in the nominative plural. With the existential есть, the thing that exists takes the nominative. Although книги can also be the genitive singular of книга, the presence of есть and the context of “having multiple books” tell you it’s nominative plural here.
