Questions & Answers about Po pracy boli mnie oko.
Because the preposition po takes the locative case when it means after.
- praca = work
- locative singular of praca = pracy
So:
- po pracy = after work
This is a very common pattern in Polish:
- po szkole = after school
- po obiedzie = after dinner
- po lekcji = after the lesson
Here it means after work or when work is finished.
Since Polish has no articles, po pracy can sometimes mean either after work or after the work, depending on context. In an everyday sentence like this, the most natural interpretation is simply after work.
