Questions & Answers about Я пью чай вместо кофе.

Why is кофе in the genitive case after вместо?

The preposition вместо always governs the genitive case to show substitution or replacement.
Examples:

• Вместо сахара я кладу мед.
• Вместо автобуса мы поехали на метро.

Why doesn’t чай change its form for the accusative case?

Чай is an inanimate masculine noun. In Russian, inanimate masculine nouns have identical nominative and accusative forms. Even though чай is the direct object of пью, its form remains чай.

Why is there no preposition before чай?

Direct objects in Russian normally appear without a preposition. Here чай answers the question “что?” (what?), so it stands in the accusative without any extra preposition.

Can I drop the subject pronoun Я and just say Пью чай вместо кофе?

Yes. Russian is a pro-drop language, so you can omit я when the subject is clear from the verb ending. Пью чай вместо кофе is perfectly natural in a casual context.

Could I say Я вместо кофе пью чай? Does word order affect the meaning?
