2. a. That grates; making a harsh sound; harsh.
3. n. A harsh sound caused by attrition.
4. n. A system of close equidistant parallel lines or bars, esp. lines ruled on a polished surface, used for producing spectra by diffraction. Gratings have been made with over 40,000 such lines to the inch, but those with a somewhat smaller number give the best definition.
