This is the 5380th most frequent Polish word.
spółką
"Spółką" means "company" or "partnership" in English, typically in a business context.
The word 'spółką' here is used in its instrumental case form to indicate the means or the object with which the action is associated.
Zajmuję się teraz spółką rodzinną.
I am currently managing the family company.
In this context, 'spółką' is again in the instrumental case, signifying the company as the entity participating in the discussion.
Rozmawiam o przyszłości z tą spółką.
I am talking about the future with this company.
Here, 'spółką' is used to describe the entity the subject became associated with, reflecting its instrumental case usage.
