Questions & Answers about Пускай счастье и удача всегда будут в этом доме.
What is the difference between пускай and пусть?
Why is the future tense verb будут used here instead of the present tense?
When making a wish about a lasting state, Russian pairs пускай or пусть with the future tense. While the present tense is often used for ongoing commands ("let them do something right now"), the future tense будут here expresses "may they be (from now on and into the future)".
Why is the verb будут in the plural form?
Because there are two subjects in this sentence: счастье (happiness) and удача (luck). Together they make a plural subject ("they"), so the verb must be the plural "they" form of the future tense of "to be".
Why is it в этом доме (Prepositional) instead of в этот дом (Accusative)?
We use the Prepositional case because this sentence describes a static location (answering "where are they?"). If we were talking about motion directed into the house (answering "where to?"), we would use the Accusative case в этот дом.
