не могли бы вы
Polite Request with Не Могли Бы Вы
Use не могли бы вы + infinitive to make polite requests. It is the standard way to ask for favors or information in formal and neutral settings.
How It Works
In Russian, framing a request with a negative particle (не) is a sign of high etiquette. It acknowledges that the person you are asking might not be able to help, which removes pressure from them.
Structure:
- не: The 'softener' particle.
- могли: The plural past tense of мочь (to be able). Even if you are speaking to one person, the plural form is used for the polite Вы.
- бы: The conditional particle that turns 'could' into a hypothetical request.
- вы: The formal/plural 'you'.
- Infinitive: The action you want the person to perform.
While вы is the standard for Level 3, you can adapt this for friends by using ты: не мог бы ты (masc.) or не могла бы ты (fem.).

How It Connects
Learn This First
To use this polite request formula, you need to understand how the conditional mood is formed using the particle 'бы' and the past tense. Specifically, you need the plural past tense form 'могли' to agree with the polite 'вы', followed by the infinitive of the action you are asking someone to perform.
