Questions & Answers about Będziemy rozmawiać u mnie ze wszystkimi.
What case is wszystkimi and why?
It is the Instrumental case of wszyscy (everyone). We use the Instrumental case here because it follows the preposition z/ze when it means "with".
Why is it ze instead of just z?
The preposition z (with) changes to ze to make pronunciation easier before certain consonant clusters, especially those starting with w, z, s, ś, or ź. Here, it helps you avoid choking on the thick "z-wsz" sounds and transition smoothly into wszystkimi.
How does u mnie mean "at my place"?
Literally, u mnie means "at me", but it is the standard Polish idiom for "at my place" or "at my house". The preposition u always takes the Genitive case, which is why the pronoun ja (I) changes to mnie.
Why use the imperfective rozmawiać (to talk) here instead of a perfective verb like porozmawiać?
Using the imperfective future będziemy rozmawiać focuses on the ongoing process of the activity—it translates closer to "we will be talking" or "we will be chatting". If you used a perfective verb (like porozmawiamy), it would mean "we will have a talk" or "we will discuss a specific matter", focusing on completing the conversation.
