Learn Polish: Czy sport cię interesuje? - Does sport interest you?

In this Polish sentence, sport is the subject, just like in the English translation 'Does sport interest you?'. Because sport is doing the action, the verb takes the third-person 'it' form (interesuje).

Why do we use cię instead of ty for 'you'?

Ty is the subject form, used when 'you' are doing the action. In this sentence, 'you' are receiving the action (you are the object being interested). Therefore, we use the accusative (direct object) form, which is cię.

Why is cię placed before the verb rather than at the end of the sentence?

In Polish, short pronouns like cię generally avoid the very end of a sentence. They usually tuck into the middle, right before or after the verb. Saying Czy sport interesuje cię? sounds a bit unnatural to a native speaker compared to Czy sport cię interesuje?.

Is this how I would usually say 'Are you interested in sport?' in Polish?

Yes, this is a very natural way to express that idea! While Polish does have a literal equivalent to 'Are you interested in sport?' (Czy interesujesz się sportem?), it requires more advanced grammar. This sentence ('Does sport interest you?') is just as common and much easier for beginners to use.
