This is the 16485th most frequent Polish word.
wiec
"Wiec" means "rally" or "assembly" in English, often referring to a public gathering or meeting.
Here, "więc" provides a conclusion or resolution to the speaker's state of uncertainty, leading to the decision to seek help.
Nie wiem, co zrobić, więc zapytam o pomoc.
I don't know what to do, so I will ask for help.
The word "więc" is used here as a conjunction to indicate cause and effect, linking the reason (needing to go to the store) with the resulting action (putting on shoes).
Muszę iść do sklepu, więc ubieram buty.
I need to go to the store, so I am putting on shoes.
In this sentence, "więc" serves as a logical connector implying that the second statement (we can have a picnic) follows naturally from the first statement (the weather is beautiful).
