Questions & Answers about Вы помните наш старый дом?
Why does the verb end in -ите instead of -ете?
The dictionary form of this verb is помнить (to remember). Because it ends in -ить, it belongs to the second conjugation group. For second conjugation verbs, the Вы (you) ending is -ите. If it were a first conjugation verb, it would usually end in -ете.
Where is the word for "Do" in the Russian sentence?
Russian doesn't use helper verbs like "do" or "does" to form questions. You simply take the normal statement and add a question mark at the end. When speaking, you just raise your voice pitch on the key word.
Since "our old house" is the direct object, why didn't наш старый дом change its endings?
The phrase is actually in the accusative case, which is used for direct objects! However, дом (house) is a masculine, inanimate (non-living) noun. For masculine inanimate nouns, the accusative case looks exactly the same as the dictionary form. The words наш (our) and старый (old) match this, so they don't look changed either.
Does Вы mean one person or multiple people here?
It could be either! Вы is the plural "you" (talking to a group of people), but it is also the formal "you" (talking to a single person respectfully, like a stranger or an elder). The verb form помните is the exact same for both uses.
