The term 'circular plate' can be described by two crossword solutions, 'DISC' and 'DISK'. A DISC is a flat, round object that is usually made of metal, plastic, or paper. It is typically used for storage, such as CDs, DVDs, and Blu-ray discs. A DISK is similar to a DISC, but it is usually thicker and has a hole in the middle. It is often used for spinning, such as a Frisbee or a spinning top. Both discs and disks are circular plates, and they are commonly used in everyday life.
