Questions & Answers about У вас есть вопросы?
Why do we use вас instead of вы?
In Russian, to say "you have", we use a structure that literally means "by you there is". The preposition у (by/at) forces the pronoun that follows it into the Genitive case. Therefore, the standard form вы (you) changes to its Genitive form, вас.
What is the exact role of есть in this sentence?
The word есть means "is" or "exists". The full construction у вас есть literally translates to "by you there exists". This is the standard way to express possession or having something in Russian.
Since вопросы (questions) is plural, why doesn't есть change to a plural form like "are"?
In this specific "having" construction, the word есть acts as a fixed word meaning "there exists". It does not change form based on whether you have one thing or multiple things. You use the exact same есть for singular and plural objects.
How does this sentence show it is a question, since it doesn't start with a word like "Do"?
Russian doesn't use helper verbs like "do" to make questions. The statement "You have questions" and the question "Do you have questions?" use the exact same word order: У вас есть вопросы. To ask the question, you simply raise the pitch of your voice on the key word when speaking and add a question mark in writing.
