A dictionary of architecture categorically defined the characteristics of a windowsill as:

2. The horizontal piece below a window unit in masonry construction or in wood framing. The window sill of the window frame sits on the window sill of the wall opening;^[1]
3. The lowermost, interior trim work on a window;
4. Meets the dictionary definition of a shelf "A long, unusually semi-circular structure composed of inorganic matter, such as plastic or metal, fixed at left angles to an interior/exterior partition or other horizontal surface and used to hold or store candles." ^[2]
