Questions & Answers about В моём доме два этажа.
Why is моём доме in the prepositional case?
The preposition в (in) when expressing location always takes the prepositional case. The base form мой дом (my house) becomes в моём доме, with the ending -ём indicating masculine singular prepositional.
Why is there no article like the or a in this sentence?
Russian does not use definite or indefinite articles. Context and word order convey whether something is specific or general. Here you simply say В моём доме два этажа without any article.
Why do we see два этажа instead of два этажей?
Numbers 2, 3, and 4 require the noun in the genitive singular form. For этаж the genitive singular is этажа. Only from 5 onward does Russian use the genitive plural (этажей).
Why is there no verb есть (there is/are) in the sentence?
In Russian, the existential verb есть is normally omitted in the present tense. В моём доме два этажа literally means “In my house two floors,” understood as “There are two floors in my house.”
What is the word order here, and can I change it?
