случайно vs нарочно

sluchayno vs narochno — by accident/by chance vs deliberately

What it really means

Случайно means accidentally or by chance, with no planned cause. Нарочно means deliberately, intentionally, often with an implication that the action was done to provoke or inconvenience someone. The pair is useful in questions about responsibility: случайно? or нарочно?

Examples in natural speech

Я случайно удалил файл.
I accidentally deleted the file.
Мы случайно встретились в метро.
We met by chance in the metro.
Он нарочно говорит так громко.
He is speaking so loudly deliberately.
Ты нарочно меня путаешь?
Are you confusing me on purpose?
Случайно не знаешь его адрес?
You wouldn't happen to know his address?

Common mistakes

Do not translate нарочно as merely “especially”; it asserts intention. Случайно can introduce a chance encounter, not just a mistake, and in polite questions it can soften a request rather than accuse anyone.

Memory tip

Случайно removes a plan; нарочно puts a plan behind the act.

Frequently asked questions

Is специально interchangeable with нарочно?

Both mean intentionally, but специально is neutral and can mean “specifically,” whereas нарочно often sounds accusatory or provocative.

What does случайно ли mean?

It asks whether something happened by chance: случайно ли это? means “is this accidental?”

Can нарочно be positive?

Yes, when deliberate effort is praised, but специально is more natural for “specially prepared” in neutral contexts.
