This is the 10610th most frequent Polish word.
dokończony
"Completed" or "finished."
Here 'dokończony' serves as an adjective describing something that has been finished or brought to completion, specified by the preceding auxiliary verb 'został'.
Projekt został dokończony wczoraj.
The project was completed yesterday.
In this sentence, 'dokończony' again functions as an adjective, describing the state of the report after completion, providing a conditional clause context.
Posprzątaj pokój, kiedy raport będzie dokończony.
Clean the room when the report is completed.
In this example, the verb 'dokończać' is in its infinitive form, conveying the action of finishing something, juxtaposed against the adjective form in the main clause.
