пока vs пока не

poka vs poka ne — while/until/bye vs until something happens

What it really means

Пока has several meanings: "while," "for now," or the conversational goodbye "bye." In a time clause it can mean while or until, depending on the verb and context: "Пока я работаю..." (While I work...) and "Подожди, пока я приду" (Wait until I arrive). Пока не adds negation and means "until ... not" — until an event happens: "Не уходи, пока я не вернусь" (Do not leave until I return).

Russian uses the apparently negative form пока не for a positive endpoint. The subordinate verb is often imperfective for an ongoing threshold or perfective for the completed event that marks the endpoint.

Examples in natural speech

Пока я готовлю, накрой на стол.
While I cook, set the table.
Подожди, пока я вернусь.
Wait until I come back.
Не уходи, пока я не позвоню.
Don't leave until I call.
Я не успокоюсь, пока не узнаю правду.
I won't calm down until I learn the truth.
Пока что всё хорошо.
For now everything is fine.
Пока!
Bye!

Common mistakes

Do not translate the не in "пока не" as a literal English negation: "Не уходи, пока я не приду" means "Do not leave until I come." Russian also uses positive пока clauses such as "Жди, пока я приду"; the negative form is especially common when the main clause is negative or the endpoint is framed as not yet reached.

Memory tip

Пока sets the time frame; пока не marks the event that must happen before the next action.
