This is the 14044th most frequent Polish word.
powiedzia
"Powiedzia" is not a standalone word in Polish; it is likely a truncated form of "powiedział" (he said) or "powiedziała" (she said).
Here, 'powiedziała' is used as the past tense third-person singular form of 'powiedzieć,' meaning 'to say.' The sentence expresses an action completed in the past where Maria conveyed information.
Maria powiedziała, że przyjdzie na spotkanie.
Maria said that she would come to the meeting.
'Powiedziałeś' is the masculine past tense second-person singular form of 'powiedzieć,' used to inquire if the addressed person conveyed something during an event.
Czy powiedziałeś coś interesującego podczas prezentacji?
Did you say something interesting during the presentation?
While 'powiedzieć' generally means 'to say,' here 'mówił' is used as the continuous action form of 'mówić,' related to saying but emphasizing speaking or narrating over a period of time.
