Questions & Answers about Czasem nudzę się w domu, więc idę na spacer.
Both czasem and czasami mean sometimes and are almost always interchangeable in everyday speech.
- czasem – slightly shorter and very common in spoken Polish
- czasami – also very common, maybe a tiny bit more neutral or careful in tone
In this sentence you could say:
- Czasem nudzę się w domu, więc idę na spacer.
- Czasami nudzę się w domu, więc idę na spacer.
Both are correct and natural.
się is a reflexive particle. It often corresponds to myself / yourself / oneself or just makes a verb reflexive in Polish.
- nudzić się = to be bored / to get bored
- nudzić kogoś = to bore someone
So:
- nudzę się = I am bored / I get bored
- nudzę dzieci = I bore the children
Without się, the meaning changes: you are the one causing boredom in others, not feeling bored yourself.
