The flat, narrow shelf at the bottom of a window frame. People often use it to hold plants, decorations, or small items.
A compound of 'window' and 'sill', where 'sill' comes from Old English 'syl', meaning a base or foundation. It literally names the supporting ledge under the window.
The windowsill is like a tiny stage at the edge of indoors and outdoors. It’s one of those everyday architectural words that quietly shapes how we use our space.
