Learn Hardcore Russian: Завтра я воспользуюсь скидкой и куплю телефон. - Tomorrow I will take advantage of the discount and buy a phone.

Воспользуюсь is the first-person singular future form of the perfective verb воспользоваться, meaning “to make use of” or “to take advantage of.”

How does воспользоваться differ from пользоваться?

Пользоваться is imperfective, indicating habitual or ongoing use (“to be using”). Воспользоваться is perfective, focusing on a single completed action of taking advantage of something.

Why is скидкой in the instrumental case?

The verb воспользоваться requires its object in the instrumental case to express “using” or “making use of” something. Hence скидкой (“with the discount”).

Why is there no preposition before скидкой?

Certain verbs in Russian, including воспользоваться, directly govern the instrumental case without any preposition.

Why are both воспользуюсь and куплю perfective and in the future tense?

Perfective verbs can only form a simple future (one-word future), emphasizing completed actions. If you used imperfective (пользоваться, покупать), you’d need a compound future (e.g., буду пользоваться, буду покупать) and it’d imply ongoing or habitual actions rather than a one-time plan.

Why is телефон in the accusative case?

Телефон is the direct object of куплю. Inanimate masculine nouns have identical nominative and accusative forms, so it stays телефон.

Can you omit я in this sentence?

Yes. Russian often drops the subject pronoun when the verb ending already indicates who is acting. You could simply say Завтра воспользуюсь скидкой и куплю телефон.

Does the word order matter here?

Russian word order is relatively flexible. The given order (time – subject – verbs – objects) is neutral. You could also say Завтра я куплю телефон и воспользуюсь скидкой, but that might slightly shift the focus or emphasis.
