Explanation

When something is grating, it's extremely harsh and irritating, like the grating sound of your alarm clock early on a Monday morning. As an adjective, grating is particularly good for describing unpleasant sounds, like the grating voice of someone who's nagging you. As a noun, a grating is an object in the shape of a grid, with parallel bars forming regular squares or rectangles. This kind of grating is often used as a cover for an opening, like the grating that covers a storm drain in the gutter or an exhaust fan in the ceiling.
