This is the 4870th most frequent Polish word.
otworzyć
"To open."
The word "otworzyć" here means "to open" and is used in a literal sense of physically opening an object, in this case, a window.
Chcę otworzyć okno.
I want to open the window.
In this context, "otworzyć" is used metaphorically to indicate becoming receptive or open to new thoughts or perspectives.
Musimy otworzyć się na nowe pomysły.
We need to open ourselves up to new ideas.
Once again, "otworzyć" means "to open" here, but it is used in the sense of asking someone to perform the action of opening the door.
