Questions & Answers about Myślę, że goście przepłacili za hotel.
How does the prefix prze- change the meaning of the base verb in przepłacili?
The base verb is płacić (to pay). As covered in this lesson, the prefix prze- applied to a verb often indicates excess, crossing a limit, or doing too much of something. Here it turns 'to pay' into 'to overpay' (przepłacić).
Why do we use the perfective verb przepłacili instead of the imperfective przepłacali?
The speaker is referring to a single, completed transaction: the guests paid the bill and it is done. If we used the imperfective przepłacali, it would imply an ongoing or habitual action, meaning they were in the continuous process of overpaying, or that they regularly overpay for hotels.
What rule dictates the grammatical case of hotel here?
When you pay 'for' something in Polish, the preposition za is followed by the accusative case. Because hotel is an inanimate masculine noun, its accusative form looks exactly the same as its dictionary (nominative) form.
Why does the verb end in -li (przepłacili) instead of -ły?
