ludźmi

In a sentence

• Rozmawiam z ludźmi o ważnych kwestiach.

  I talk to people about important matters.

  The word 'ludźmi' is the instrumental plural form of 'ludzie', meaning 'people', used here as the object of 'z' (with) indicating the means or companionship in the action.

• Pracuję nad projektem z ludźmi z różnych krajów.

  I am working on a project with people from different countries.

  In this sentence, 'ludźmi' again serves as the instrumental plural form being used to express participation or association with 'z' (with).

• Musimy współpracować z dobrymi ludźmi, aby osiągnąć cel.

  We must cooperate with good people to achieve the goal.

  Here 'ludźmi' follows 'z' (with) to indicate collaboration, again utilizing the instrumental plural form to denote roles or participants in an action.
