Questions & Answers about Właśnie wróciłem z pracy.
I learned that tylko means "just". Why is "just" translated as właśnie in this sentence?
Is the speaker of this sentence male or female?
Doesn't z usually mean "with"? Why does it mean "from" here?
The preposition z has two entirely different meanings depending on the grammar case that follows it. When you use it with the Instrumental case, it means "with". But when you use it with the Genitive case—as it is here—it means "from" or "out of".
Why is the word for work pracy instead of the dictionary form praca?
Because the preposition z (when meaning "from") forces the next word to be in the Genitive case. For feminine nouns ending in -a like praca, the Genitive ending is usually -y, which makes it pracy.
