IPA: /ˈwɪn.doʊ/
KK: /ˈwɪndoʊ/
An opening in a wall or structure that is usually filled with glass, allowing light and air to enter a room.
She looked out the window to see the beautiful garden.
The word 'window' originates from Old Norse 'vindauga', which is a compound of 'vindr' (meaning wind) and 'auga' (meaning eye). Thus, a window is literally an 'eye for the wind', allowing air and light to enter a space.
Think of a window as an 'eye' ('auga') that lets in 'wind' ('vindr') — that's why it serves as an opening for air and light.
