Questions & Answers about Silnik jest zepsuty, zatem musimy go naprawić.
Could I use więc instead of zatem in this sentence?
Yes, absolutely! Both express a logical consequence. The difference is mainly in tone: zatem sounds a bit more formal or analytical, like English 'therefore' or 'thus', while więc is your everyday 'so'. A mechanic giving you an official diagnosis might use zatem, but chatting with a friend you'd probably just say więc.
I thought go meant 'him'. Why does it mean 'it' here?
The word silnik (engine) is a masculine noun. In Polish, the accusative (direct object) pronoun for a singular masculine noun is go, regardless of whether it's a person ('him') or an inanimate object ('it'). Even though masculine inanimate nouns don't change their own endings in the accusative case, they still use go as a pronoun.
Why do we use the perfective verb naprawić here instead of the imperfective naprawiać?
We use naprawić because the goal is to get the engine completely fixed. Perfective verbs focus on the completion or result of an action. If you used naprawiać, it would mean 'we have to spend time working on it' without necessarily emphasizing that the job actually gets finished.
Could we say zepsuł się instead of jest zepsuty?
