A sheet is a large, wide amount of something flat, like a sheet of metal or a sheet of paper. When it goes on your bed, a sheet is a similar expanse of fabric.

The sheets on your bed cover your mattress and lie beneath your blanket or comforter, and the huge windows in your imaginary dream house would require enormous sheets of glass. Sheet music consists of musical notation written on sheets of paper, and a sheet of rain comes down so hard it looks like a solid surface. If it rained overnight and the water froze on the ground, you might say, "Careful, it's a sheet of ice outside!"
