Questions & Answers about Kiedyś jadywaliśmy w tej kawiarni w każdy piątek.
What is the exact difference between jadywaliśmy and jedliśmy here?
While jedliśmy is the standard imperfective past meaning we were eating or we ate, jadywaliśmy is a frequentative verb. The suffix -ywać specifically adds the meaning of a repeated, habitual action in the past, translating nicely to we used to eat.
How do we get the form jadywaliśmy from the basic verb jeść?
The underlying root of jeść is jed-, which you can see in forms like jedzą (they eat). To build the frequentative form, the root vowel e changes to a to make jad-, and then we add the suffix -ywać to create the infinitive jadywać.
Since jadywaliśmy already means we used to eat, isn't kiedyś redundant?
It might seem redundant, but combining them is very natural in Polish. Kiedyś simply sets the timeframe right away to mean once or back in the day, while the frequentative verb emphasizes the habitual nature of the routine.
Why do we use the accusative case for w każdy piątek but the locative case for w tej kawiarni?
